Duck eggs vs chicken eggs
Many medical studies and research have dealt with chicken eggs with analysis and evaluation, sometimes revealing its health benefits and others warning about it, while most researchers agree that eating one egg a day has many benefits and does not cause any harm, but have you tried or asked yourself : duck eggs vs chicken eggs ?Difference 1
Duck eggs are larger than chicken eggs, with an average weight of about 70 grams per egg compared to 50 grams for chicken eggs. Of course, being bigger means that “each egg” is looking for calories and other nutrients (9 grams of protein in a duck egg, 6 grams in a chicken egg, but roughly the same thing in the same unit of shelled eggs).
Difference 2
Duck eggs contain relatively more egg yolks than chicken eggs, making them relatively more calorie-dense, with greater amounts of nutrients found in the egg yolk versus the white (such as fat-soluble vitamins).

If the duck eggs incubated, you will need to do this for 28 days and the ducklings will come out. If they incubated the chicken eggs, you will need to do this for 21 days and the chick will emerge.
Difference 4
Duck eggs have a stronger flavor. If you like eggs then you probably will love duck eggs, but if you like "meh, I use eggs as an excuse to eat sauce / cheese / whatever" then you probably won't be a huge fan. Personally, I like using duck eggs in egg-centered baking to make the final product richer (flan is my favorite).

NB :
Peking duck is an ancient dual-purpose duck breed. It originated in China and is now one of the most popular commercial duck breeds. Duckling was born in China.
Peking duck is also known by other names, such as the American peking duck or the Long Island duck. Sometimes it is wrongly written as a Peking duck. The breed was brought to the Western world in the mid-nineteenth century.
Peking duck is now the most prolific breed of commercial meat duck in the United States. Their ability to lay eggs and good quality of meat made them the first choice of American duck farmers. Today the Peking Duck is very popular and is available all over the world.
Duck eggs
Duck egg is commonly produced in China and Southeast Asia, and it is considered a protein-rich and low-cost source at the same time. Compared to the size of chicken eggs, it is about 50% larger, and the yolk of duck eggs is also distinguished by being Large in size and golden in color, in addition to having a creamy texture and creamy flavor that many people prefer, and although the color of chicken eggs is limited to white or brown, the colors of duck eggs are different, and they range from pale blue, green blue, or grayish-colored Charcoal, or white color, and one of the most important differences with chicken eggs is that it provides a higher percentage of some nutrients important to the health of the body, including: Protein.
Benefits of duck eggs
The following points explain the benefits of duck eggs according to their nutrient content :
Rich source of protein: duck eggs contain the highest quality protein. That is, what provides all the essential amino acids that the body needs to make proteins.
Rich source of antioxidants : such as carotenoids; Carotene, cryptoxanthin, zeaxanthin, and lutein, which provide the yolk of duck eggs with a yellow-orange color, and these antagonists are compounds that may reduce the risk of damage to cells and DNA as a result of oxidation processes, which may lead to some chronic diseases and associated diseases With age.
A rich source of choline: The yolk of duck's eggs is one of the sources rich in choline, a food substance that enhances many different body functions, such as; Cell growth, metabolism, and it should be noted that the body produces a small amount of this nutrient while most of it comes from consuming foods rich in it.
A source rich in minerals : compared to chicken eggs, and as mentioned earlier at the beginning of the article, duck eggs provide the body with a higher percentage of nutrients, including minerals, as it provides 52% of the daily needs of selenium, compared to 45% provided by chicken eggs, while That the daily amount of iron provided by duck eggs is 21%, which is nearly twice what is available in chicken eggs. As it provides 10% of the daily amount of this mineral, [2] in addition to some other minerals, as it provides the body with 15% of the daily amount of phosphorus, and 7% of the daily amount of zinc.
Damage to duck eggs
The degree of safety of duck eggs
The risk of exposure to salmonella bacteria is higher in some groups, including; Infants, children, pregnant women, the elderly, and others who have a weak immune system, they should avoid eating raw or undercooked eggs.
Precautions for using duck eggs
The following points explain some of the caveats associated with consuming eggs :
The risk of high cholesterol levels: Diabetics, and those with a family history of heart disease, are advised to be careful and careful when consuming egg eggs, because they contain a high level of cholesterol.
The risk of developing an egg allergy: The consumption of eggs is one of the most common causes of allergy in children, and it should be noted that some of them can overcome this sensitivity before reaching the stage of adolescence, and the symptoms of egg allergy range from simple to severe or what is known as anaphylaxis (Anaphylaxis), and the most common symptom is skin allergy, while other symptoms include; Runny nose, itching, tears, cramps, nausea or vomiting, and one of the best ways to control and relieve egg allergy is to avoid eating all foods that contain eggs or egg products.
What are the benefits of duck eggs for children
There is no information available about the benefits of duck eggs for children specifically, but it is worth noting that eggs may be an important part of a healthy diet for children, as it provides them with nutrients necessary for their health, and according to the Dietary Guidelines for Americans, eggs belong to a group of Protein foods along with other seafood, poultry, soy foods , nuts and seeds, and red meat , and it has been shown that children between the ages of nine to thirteen years need to consume an amount ranging from 5 to 6 servings of this food group daily, While the younger children may need between 2 to 4 portions of the same group, it should be noted that one portion is equivalent to about 28.3 grams.
Nutritionists emphasize the importance of chicken eggs, as eating them regularly has many benefits for the human body.
Chicken eggs help in getting rid of excess weight, in addition to being a food item that makes a person feel full for a long time, because it contains vitamins and elements beneficial to the body, and egg white helps in the formation of muscles.
Chicken eggs prevent the feeling of fatigue that appears during the period of work, because they contain fats, indispensable amino acids and vitamin В12. These substances help produce the energy necessary for both physical and intellectual activity.
Also, chicken eggs help maintain visual acuity and eye health because they contain antioxidants such as lutein and zeaxanthin, which prevent eye diseases such as cataracts, macular degeneration and blindness.
What happens if a person eats eggs daily ?
Chicken eggs improve cognitive functions, because they contain a compound choline, which helps in forming cell membranes that play the role of a filter (filter) for brain cells, preventing toxins from entering them. The body uses this compound to regulate nervous system activity and memory processes.
Among the benefits of chicken eggs also is that it reduces inflammation in the body, as the choline complex, antioxidants and amino acids in it stand against the processes that cause cell and tissue infections, especially since eating chicken eggs activates the process of excreting the waste that reaches the blood with food, drink and medicines.
Finally, chicken eggs boost the immune system because they contain nutrients needed for the production of antibodies.
Studies on the benefits of eggs
A laboratory study published in Agricultural and Food Chemistry in 2010 in animals indicated that egg yolk peptides reduce oxidative stress by increasing the concentration of antioxidant enzymes in red blood cells. A study published in the Journal of Agricultural and Food Chemistry in 2009 and conducted on animals indicated that the enzyme lysozyme (Lysozyme) found in chicken eggs helps to restore intestinal balance by activating the regulatory T cells (Regulatory T cells). Which is important for regulating the mucous immune system, and in addition to it has anti-inflammatory activity , it reduces inflammation-inducing cytokines. A study published in Comparative Biochemistry and Physiology in 2001, which was conducted on mice, showed that oligopeptide extracted from chicken egg yolk has antihypertensive activity , and this effect may occur by inhibiting the activity of the angiotensin converting enzyme (ACE).Angiotensin-converting enzyme).
Eggs and heart disease
The results of studies are conflicting about the relationship between eating eggs and increasing the risk of various heart diseases, as high levels of cholesterol in the blood increase the risk of heart disease, and although eggs contain cholesterol, the amount of saturated fats usually has a greater effect on the amount of Cholesterol in the blood, compared to the amount the body gets from eating eggs. [28] A systematic review of 40 studies published in The American Journal of Clinical Nutrition in 2015 on 361,923 people indicated no relationship between cholesterol consumption, cardiovascular disease, including coronary artery disease , ischemic or ischemic stroke, and hemorrhagic stroke. , [29] but on the other hand , pointed out a recent study published in the Journal of the American Medical Association Journal in 2019, to increase the consumption of eggs and cholesterol, associated with an increased risk of heart disease and blood vessels , and depending on the quantity eaten. [30] [31] Most people are advised not to consume more than one egg per day, in order to avoid the risk of a heart attack, stroke, or any other type of cardiovascular disease, but people with diabetes or at risk of heart disease for other reasons, such as Smoking , or those already suffering from heart disease, should not exceed three eggs per week, [32] and people who follow a balanced diet may ask their doctor or dietitian to reduce their intake of eggs to monitor blood cholesterol levels.
Common questions about eggs
How many calories are in a boiled egg ? The calories depend on the size of the egg, as a small egg contains less than approximately 72 calories, and a large egg contains a little more.
Are there benefits to ground eggshells
Egg shells can contain salmonella bacteria , and the diseases caused by this bacteria are dangerous for some people, such as children under the age of 5 years, people over the age of 65 years, in addition to people with weak immune systems, such as those with HIV HIV, AIDS, diabetes, or those who have undergone an organ transplant. However, a study published in the journal Maternal & Child Nutrition in 2018 indicated the possibility of using egg shells as a calcium supplement, as it is possible to take some measures to get rid of the bacteria on the eggshells, and in this case only scientists may use them for children and women who are deficient in Calcium levels in poor countries, [35] and another study published in the International Journal of Clinical Pharmology Research in 2003 indicated that ground eggshells have a positive effect on bones and cartilage, and may reduce the risk of osteoporosis and improve the incidence of Infected patients, but as previously mentioned this is being done under medical supervision.
Duck eggs vs chicken eggs | How do chicken eggs hatch
Raising chickens
Raising chickens at home or on the farm is one of the easy projects that can be implemented simply when all the necessary needs are met, all that is needed is enough space, providing chickens of a good breed that desires to lie on eggs, and providing a rooster for every twenty chickens to get a plurality of fertilized eggs; The unfertilized eggs never hatch, and fertilized eggs can be purchased from other farms in the absence of a rooster at home, and the eggs can be hatched by allowing the mother hen to lie on the eggs, or by using an incubator.
Hatching eggs With the natural nursery
Eggs can be hatched naturally if the mother hen is of a strain that has the ability and desire to lie down on eggs and incubate them throughout the day, and leave them only once to eat food and water, and relieve their need, and in this case all that the breeder has to do is provide a box that the hen uses as a nest for incubation Eggs, to be large enough for the hen to move and turn around during the incubation of eggs, and for the chicks to be able, as soon as they emerge from the eggs, to comfortably access water and food, and a square foot size box is quite appropriate. The nest box shall be lined with straw or sawdust to make it more comfortable for the mother and the eggs, and it is preferable to put fodder and water near the box throughout the incubation period of the eggs. In order for the mother to be able to remove the eggs, eat her food and return quickly. [2] Chickens eggs need 21 days to hatch, and often they do not all hatch once, but rather needs between two to four days, and the eggs that do not hatch after this period must be discarded; Because it will most likely not be good, and these eggs can be removed while the mother hen is sleeping to avoid being bitten. Chicks that hatch naturally do not need much maintenance. The chicks are able to regulate their own temperature, they hide under the mother’s wings when she feels cold, and they come out when she feels overheated, and when the mother feels that there is a danger to the chicks, she will immediately make special sounds to warn her, so she comes quickly to hide under the mother's hen, and the breeder must during this The period Provides fresh food and clean water for the mother and the chicks, and the mother can transfer the chicks to the nursery area after making sure that the rest of the chickens will not behave aggressively towards her chicks.
Using the incubator
In some cases it is difficult to rely on the natural incubation of eggs hatching; Especially if the mother hen of the breed does not favor lying eggs throughout the incubation period, or if there is a large number of eggs so that it becomes difficult for the chicken available custody, in this case can be used as industrial incubator for hatching eggs, and be done by following the following steps :
Buy an incubator whose size is proportional to the number of eggs to be incubated, taking into account that only 50-70% of the eggs will hatch, and that half of the number of chicks will be males, and it is necessary to make sure that the temperature and humidity of the incubator can be controlled, and an incubator can be made instead of buying it. Carefully collect eggs using a straw-lined basket; In order not to break, and to protect its membrane and internal parts, and take care to wash hands before collecting it; To ensure that bacteria are not transferred from the hands to it. Clean the nest regularly; To get rid of mud and dung that may increase the growth of harmful bacteria to eggs. Selecting eggs to be incubated, and excluding those that are larger than usual; Because it is difficult to hatch, as well as eggs that are smaller than usual; Because it hatches small chicks that will not be able to survive, and avoid eggs that contain cracks, or whose shells are thin, or eggs that have an abnormal shape, and take care to choose clean eggs and exclude dirty, while avoiding not washing eggs; This removes the protective layer of the peel, making it less resistant to bacteria. Keeping eggs for 24 hours in a place with high humidity and a temperature of 13 ° C before starting to incubate them; So that the pointed side of the egg is down, and eggs can be kept for a longer period before incubating them, provided that the period does not exceed seven days, taking care to turn the eggs daily. Put the incubator in a cool room, and avoid placing it near a heat source, or near windows or doors. Heat the incubator several hours before starting the incubation of eggs to reach the appropriate temperature and humidity. If the incubator is equipped with a fan, the incubator can be set at 38 degrees Celsius, and if it is not equipped with a fan, it should be set at 39 degrees Celsius. As for the humidity, it should be 40% in the first 18 days, and raised by 60-70% during the last three days before hatching. Placing eggs in the incubator, making sure that the pointed side is not facing up; Because the embryo will not develop properly in this case, and it will be subject to death before hatching. Rotating the eggs inside the incubator five times a day very gently. To avoid damaging the fetal tissue, taking into account that the egg is not rotated in the same direction every time. It will be useful to mark the eggs before starting to incubate them to know the direction of egg rotation, and the egg rotation must be stopped in the last three days prior to hatching, and the incubator should not be opened completely by that time. Examine the eggs with a flashlight shone on the egg in a dark room. To make sure the fetus is developing properly. The blood vessels can be seen several days after the start of the incubation, and the fetus can be seen on the seventh day. The eggs that do not undergo any development between the tenth to the fourteenth must be discarded. Opening the ventilation holes slightly to supply the incubator with more oxygen when the eggs start cracking is noticed, and the chicks are not helped to hatch; Because chicks that do not hatch on their own usually die before reaching adulthood. Transfer the chicks to the nursery box after the hatching of all the chicks has been completed, provided that the box is placed away from air currents and cats, and the box is provided with a lamp to warm the chicks. Chicks need a temperature of 99 degrees Fahrenheit for the first week, dropping by 5 degrees every week until they reach normal room temperature. The chicks do not need to be fed for 48-72 hours after hatching, after which they must be provided with clean water and food intended for the chicks until they reach adulthood, at which time they can begin to accustom them to the usual chicken food gradually.
How to take care of chickens
Daily care Daily care of chickens is necessary, and is done by following the following steps :
Make sure to provide daily clean water, and disinfect water containers if necessary. Securing large hanging food units, or providing specific quantities of food on a daily basis. Get rid of damaged eggs , and collect eggs daily. Spend time observing the chickens to ensure their health by observing their feathers, eyes, and physical activity.
Monthly care The monthly tasks in caring for chickens are as follows:
Change the straw that the chickens sleep on, according to the cleaning method used; It must be changed at least once if the place is in residential neighborhoods, but for large groups of chickens, it is recommended to replace straw, and to put a layer about ten centimeters thick when the stool collects on it, then collect it and use it as fertilizer because of its richness in nitrogen. Clean chicken sleeping boxes from damp and hard straw and egg scraps. Cleaning the water containers, rubbing them with dishwashing liquid, then rinsing them well, sterilizing them, and one of the easiest sterilization solutions that can be used is bleach. It is prepared by mixing one part of bleach with ten parts of water, and sterilizing the boxes with it.
Annual sponsorship
The annual care of chickens is done by following the following steps:
Cleaning the hen in general and disinfecting it using the aforementioned bleach solution, and spraying the soil and the roof with it also to eliminate mites, and to keep the chickens in good health. Preparing the hive for the winter season, and making sure that there is enough space for chickens to roam inside the coop; To keep it warm.
Incubator eggs
It is a machine that carries out the task of the chickens in incubating eggs to hatch and producing chicks, by providing ideal biological conditions for them, which are to regulate the temperature and humidity of the place, and it is a reliable way to obtain large quantities of eggs in a record time depending on the type, size and quality of the hatchery. In addition to saving the time that the hen incubates the eggs to get more of them, it can be bought or made by hand in the way that will be mentioned later. How to make an incubator Hand-made egg incubators can incubate a quantity of eggs ranging from 30-50 eggs, which is relative depending on the size of the container that is chosen, and on the way the eggs will be rounded, and this does not mean that the home incubator will be ineffective or its results are not guaranteed, But it needs care and attention to the vital matters that achieve its success, including: temperature, incubator humidity, and regular egg rotation, and household incubators can be made in the following way :
The incubator is made inside a polystyrene box A home incubator can be made by following the following steps :
Ingredients : Light bulb socket. An electrical extension cord to connect the lamp to the socket. A bright light bulb whose wattage depends on the size of the polystyrene box used. Polystyrene box. Cut wood with appropriate dimensions to create a frame the size of a box opening. Screws for fixing sieve and timber frame. Good quality adhesive wood glue . A piece of cloth or metal sieve of appropriate size wrap over the wooden frame. Hygrometer thermometer. A deep cup to hold the water in the hatchery. How to make : A rectangular wooden frame is made by attaching woods with nails or glue to the size of the box opening. A piece of cloth or a metal sieve is cut and wrapped around the wooden frame and fastened well with nails, taking into account that it is made of a material that bears the weight and number of eggs to be incubated inside the incubator, which will be placed on this frame. A small hole is cut on one of the sides of the polystyrene box to match the size of the light bulb to be placed in the incubator, for example, it is made at a height of 2.5 cm, or higher so that the lamp does not touch the box cover or its lower base, then it enters the lamp socket through it, and the lamp is strongly selected Convenient electrical power, 10-40 watts can do the trick because small light bulbs also fit small incubators. Make several ventilation holes in the sides of the box and 4 holes in the lid. The incubator is collected by placing the water cup on the floor base made of the wooden frame and the sieve inside the box, then the lamp is installed and the thermometer is placed inside. Initially, several eggs are placed over the sieve for the weight test. A glass hatch can be made to observe the eggs in the incubator, which is made on the outer cover of the polystyrene box, by making a wooden frame that encases a glass square of a suitable size, then cutting the ceiling and installing it on it, turning on the light and closing the ceiling, and then starting the incubation process for eggs. Follow-up incubation of eggs in incubation The process of incubating eggs is not only satisfied with making the incubator and placing it inside it, but it also needs care and attention , by following the following steps:
The process of counting and following the timing of incubating eggs regularly : it takes 21 days for the eggs of the chickens to hatch, and therefore it is necessary to know the exact day in which the incubator was made and put the eggs inside, in addition to reading the temperature of the incubator, tracking the humidity inside the incubator, and not neglecting these important vital indicators. Egg rotation : Eggs should be turned 1 / 4-1 / 2 cycle 3 times a day during the first 18 days, and you can know which side to turn over by placing a mark on both sides of the egg, one with an (X) letter and the other with an (O) letter to distinguish between them. Using an egg candle : It is a method that is used after the first week, as it allows a person to detect invalid eggs, by carrying the egg on a bright light in a dark room to see what is inside, and you can buy a special candle device, or use a small flashlight with bright lighting, If there are rotten eggs that are not suitable for hatching, they must be removed from the incubator, noting that when using a flashlight, the lens must be small enough to direct the light clearly and accurately to the egg, and the person may have to gently turn the egg up and down or from side to side. else; To better see its contents, where a living embryo appears as a dark spot from which blood vessels start, while a dead fetus may appear as a ring or blood line inside the shell, noting that a rotten egg lights up even though there is no embryo inside.
The final stage, which is hatching : The incubation process takes place as a great indicator of the success of the hand-made incubator, on the 21st day of the start of incubation, when the chicks will start hitting their feet in the outer shell of the egg, announcing their desire to go out to a wider world, but this process is not done simply and quickly. It may take up to 12 hours to break the hard shell and completely exit the egg on its own, and in the event that the time has elapsed and it is not able to break it and exit, the person can help it, remove the husks gently, and allow it to ascend to the new world.
Types of egg incubators
There are many types of egg incubators, including the following:
Forced-air incubator : These are incubators equipped with fans that distribute the warm air inside, which increases the effectiveness of hatching eggs, and allows incubating a large number of them. Conventional convection incubator : differs from the previous in terms of method of heat distribution, they contain holes and vents in the top and bottom of the incubator side, which in turn raises the hot air and pull cold Vetofr warm eggs, but they may be vulnerable to drought and must monitor moisture regularly. Constant air incubator : It is a closed incubator that does not have holes, and the heat inside is heated but the air is not circulating; Because there are no fans or openings for ventilation, and therefore eggs must be placed in the appropriate place, which is the most difficult to use , and needs great precision.
Benefits of raising chickens
In addition to the pleasure that can be obtained through raising chicks and chickens and monitoring their growth, raising chickens at home can have many benefits, including :
Get fresh eggs , and they taste better than eggs that are available in the commercial markets. Providing nutritious compost for the garden soil. Get rid of insects and weeds that are a source of food for chickens, as well as mice and snakes if the hen finds the opportunity. Your source for nutritious white meat. Provide a loving and loyal pet; Chickens are birds that have an independent and loving personality.
