Are the chicks that can be bred by double yolk eggs twins?

When we were young, we might have eaten this kind of egg, they have two yolks, and when we were young, we didn't understand why some eggs only had one yolk, but some eggs had two yolks. When I grew up, I understood that this kind of egg was called a double yolk egg. Then someone will definitely ask the question, are there two chicks born in double rows?

So now let's take a look at how eggs hatch? First of all, let's understand the structure of eggs, generally eggs are: egg white, which is what we call protein, as well as embryonic disk, yolk membrane, frenulum, and air cell to form a complete egg.

Not every egg can hatch chicks, and whether a chick can hatch depends mainly on whether the embryo of the egg is fertilized. If the egg cell is not fertilized, then the egg will not hatch a chick even if it is a double yolk egg, and no chick will be able to hatch. If this egg cell is already fertilized, then it is possible to hatch chicks.

Generally, after the fertilized egg is excreted by the hen, it will develop over a period of time, and as the embryo gradually develops, it will absorb the yolk and egg white, as its main energy**, and finally become a chick. In fact, from the appearance of double yolk eggs, they are slightly larger than ordinary eggs. The reason for this is that the double yolk egg is composed of two egg cells, while the average egg has only one egg cell, although this is the case, it does not mean that both egg cells will be fertilized at the same time.

Sometimes only one egg cell in a double yolk egg is fertilized, and the other egg cell becomes an egg cell that is fertilized by energy, which is absorbed as supplementary energy. If both egg cells are fertilized, then theoretically two chicks can hatch. However, the size of the egg is very limited, so there is a certain probability of whether two chicks can hatch, because the size of the egg limits the space for the two chicks to grow at the same time, so it is possible that the two chicks will die due to lack of oxygen or crowding before they grow up.

Double yolks are two separate fertilized eggs, similar to siblings (fraternal twins), although the double yolk is larger than a normal egg, but not twice as much, so the probability of giving birth to two chicks is still not very large.

In fact, it is more difficult to hatch chicks with double egg yolks, and it is also difficult to hatch two chicks, mainly depending on how many fertilized eggs in it have successfully developed, if two chicks are successfully hatched.

Although theoretically possible, because of the limited protein and other nutrients in the eggshell, in fact, two chicks cannot hatch, and it may even cause the chicks to die because of the adhesion of the egg yolk.

Because the space, oxygen, and nutrients in the egg are limited, the developmental needs of both embryos cannot be met at the same time. Especially as the embryo continues to develop, this "lack of resources" will become more apparent, and eventually both chicks will die.

The part of the egg that really hatches the chick is not the yolk, but the "little white dot" on the yolk. The role of the egg yolk is to provide nutrients for embryonic development, and its number has nothing to do with the number of chicks that can be hatched.

Even if there are two embryos in an egg, it is unlikely that twin chicks will hatch. This is because the space, oxygen, and nutrients within the egg are limited to meet the developmental needs of both embryos at the same time. Especially as the embryo continues to develop, this "lack of resources" will become more apparent, and eventually both chicks will die.

It is definitely impossible, it is difficult to hatch chicks from double yolk eggs, but this kind of egg should be very nutritious to eat, after all, there is an extra egg yolk.

Yes, double yolk eggs are possible, but many can only live one, so they are not common.

No, you can't hatch with double yellow eggs, you can only use single yellow eggs to hatch chicks.

I don't think so, I feel like I can only eat it.

It should be possible, but not absolutely.

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.
