What kind of chicks can hatch from double yolk eggs?

<> everyone must have eaten double yolk eggs in their daily life, from the appearance of their size is larger than ordinary eggs, in the interior is to have two egg yolks, and the egg whites will be relatively more. So have you ever wondered if double yolk eggs can hatch chicks? What would it be like to hatch chicks?

Single, two, or deformed? Let's take a look at that. <>

The egg is the egg of the hen, and it does not stop ovulation regardless of whether the hen is fertilized or not, and of course it is not to provide food for humans. The chickens on the farm are kept in a small cage every day and eat nutritious food, and the daily task is to lay eggs, and this type of hen has no possibility of touching the rooster, so it is said that all the eggs laid are not fertilized and cannot hatch, just for us to eat. <>

In the natural state of the family free-range chicken, known as "wandering chicken", every day when there is nothing to do, "wandering" will naturally meet the rooster, the rooster and the hen mating once, the hen can be fertilized for more than 10 days in a row, not all eggs can be hatched, the eggs must be fertilized before they can hatch. Selecting a fertilized egg is also very simple, and if you look at the candlelight in a darker environment, you can see what is really going on inside the yolk, and the fertilized egg has blood streaks on it. <>

If both yolks of a double yolk egg are fertilized, then theoretically two chicks can hatch, which is not the same as the same twin born in humans, and is more similar to fraternal twins. It is because of the endocrine disorder of the hen, two egg cells are produced in the ovary at the same time, and the two egg cells move down the oviduct at the same time, continue to move after fertilization at the junction of sperm and egg, and then wrap enough nutrients through the protein secretion part, and finally wrap the eggshell through the uterus, and then discharge through the cloaca. <>

Double yolk eggs can theoretically hatch two chicks, but in practice it is almost impossible to achieve, first of all, the nutrients of double yolk eggs are not enough for the formation of two chicks, even if the chicks are formed in the early stage, but they will eventually squeeze each other and die. And when the two embryos are developing, the two yolks are squeezed too close to each other, and the developed blood vessels are intertwined and mixed with each other and cannot continue to develop. Double yolk eggs are generally not selected for incubation, and the hatchability rate is too low.

The black hole of literature and science, the **** network invasion and deletion.

Answer: After fertilization, the double yolk egg can theoretically hatch chicks, but in fact, the survival rate is too low, because it is two chicks, they are intertwined with each other in the blood vessels in the eggshell, squeezing each other, it is impossible to survive.

If it is an egg that a rooster makes a hen pregnant, then one such egg can produce two chicks. If the hen produces it herself, then it will not become a chicken in the end, it will still be eaten.

Double yolk eggs cannot hatch chicks because if there are two chick embryos in the egg, it is difficult to thrive, there is not enough nutrition and oxygen, and it will suffocate and die due to lack of oxygen.

It could be that there will be two chickens in it, and there will be two bodies inside. Two pieces of meat with organs can be formed, but these two chicks may not be particularly strong, and it will be somewhat limited.

Such eggs are actually like humans will raise twin chicks, they are two yellow, then they will develop cute chicks, which is also a very magical thing.

There are many reasons for the formation of double yolk eggs, the main of which are hormone secretion, startle and genetic mutations.

First of all, double yolk eggs belong to deformed eggs, and the cause of deformity has a certain relationship with heredity and genetic mutations, but this is not the main reason for the formation of double yolk eggs. According to scientific research, hens that have just reached the age of fertility are more likely to produce double yolk eggs than hens of other ages, and this is caused by the excessive hormone secretion of hens that have just become fertile.

Secondly, some double yolk eggs are caused by the poultry being frightened, resulting in flying and jumping, which causes some follicles to burst, and the yolk in the ruptured follicle may enter other follicles through the gap in the follicle, thus forming a double yolk follicle.

Characteristics and the probability of double yolk eggs

Outwardly, the double yolk egg is larger than a normal egg, but it is less noticeable, and the two yolks inside are similar in size to a regular egg. According to scientific research, under normal circumstances, the probability of birds laying double yolk eggs is about 1, even in China, which has the "four famous ducks" and "the king of double yolk eggs", the probability of Gaoyou Ma duck producing double yolk eggs is only about 1, which shows that double yolk eggs are indeed rare.

The above inner knowledge of Xiaoqin Shen Xun Rong reference: Encyclopedia - double yolk eggs.

In most cases, double yolk eggs do not hatch chicks.

This is because double yolk eggs are larger than normal eggs, but each embryo has less room to grow than normal eggs. This, in turn, has a direct impact on the consumption of nutrients and oxygen, the movement of the fetus, and the later breakage of the shell.

This has led to a general stunted development of chicks in double yolk eggs, a weaker number, and a high threshold for breaking the shell. Moreover, the double yolk egg is not only much larger than the normal egg, but also has a thicker shell, which is more difficult to chisel through.

In addition, in the process of pecking the shell, the chick needs to change the posture of the body from time to time to change the angle of the peck shell, and the two chicks in the double yolk egg occupy almost all the space in the egg. As a result, most of them can only slowly run out of oxygen and energy, and they will die before they can grow up.

Theoretically, both yolks in the eggshell have been fertilized, and it is possible to hatch two chicks, but in real life, in practical terms, most double yolk eggs cannot hatch two chicks.

Because two chicks will live in an egg before coming out of the shell, although the double yolk egg is much larger than the normal egg, but at most it is only a fat circle, twice as large may not be, and if the space of this large circle accommodates one more chicken embryo, oxygen and nutrition will not be enough, which often leads to the death of two chicken embryos.

Even if the two chicks are about to come out of the shell, the chicks in the double yolk eggs, because of the problem of unbalanced nutrition, are generally more fragile, many chicks are stunted, and the success of breaking out of the shell is also a big problem for them.

The volume of double yolk eggs is very large, and even the shell is much harder than normal eggs, and the thickness is about twice as thick as that of normal eggs. In the process of pecking the shell, the chick needs to constantly adjust its posture to change the angle of the peck and find an easy point to peck through the eggshell as quickly as possible.

Two little yellow chickens are crowded together, basically occupying most of the space of the egg, not to mention turning over, it is very difficult to move, coupled with the weakness of the body, with their immature and weak little pointed beak can not peck the thick eggshell at all, so the end is that both chicks may be stillborn.
