How do cocks fertilize a chicken? How many chickens can fertilize a cock?

As is known, chickens can also bear eggs without a cockerel. However, in order for chicken to grow out of them, they must, of course, be fertilized. And then there's something without a male, of course, do not succeed. One of the unusual features of poultry of this variety is that the cockerels lack a penis. Rather, they have it, but in a rudimentary embryonic state. In this regard, many people have a question about how the cocks fertilize the chicken. About this and talk further.

Why the cock does not have a penis

Unfortunately, even the scientists do not know the answer to this question. When examining the fetus, it was found that at first the penis of a chicken develops quite normally. However, on the ninth day, his growth slows down, and in the subsequent and completely ceases. This is due to the active work of the Bmp4 gene, which controls the program of cell death. Usually in the body of animals and humans Bmp4 is responsible for preventing uncontrolled cell division (and, consequently, development of cancer tumors).

The mechanism of stopping the growth of the cock's penis, thus, scientists has been studied. However, there is still no answer to the question of why the Bmp4 gene is activated at the tip of the genitalia of the embryo of the bird. There are only a few versions that more or less believably explain this phenomenon. Some scientists believe, for example, that the concentration of the Bmp4 gene on the tip of the embryo penis is somehow connected with its presence in the beak of the embryo. In the latter case, he is responsible for restraining the growth of teeth, which chickens do not need.

There is another rather convincing version, according to which the containment of the growth of the reproductive organ in embryos is the result of natural selection and hyperactivity of cocks. Some researchers believe that the chickens preferred to choose males with a smaller penis in the course of evolution for a long time. As a result, it turned out that the sexual organ at their knights completely atrophied.

How Cocks Fecundate a Chicken

Physiological process of pairing in this bird looks like this:

  • The cock starts chasing the yard for the lady he likes;
  • Overtaking a hen, he dances on her back, as they say, tramples on her;
  • While he presses his cloaca to the cloak of her friend;
  • With a short-term contact of this kind and a transfusion of seminal fluid occurs.

Below you can see how the cock fertilizes the chicken. The photo demonstrates this visually. As you can see, despite the fact that there is no penis in the males, this process in the chickens does not represent anything special in itself.

The device of the reproductive system

So, as the cocks fertilize the chicken, we think you are more or less clear. Now let's see how, actually, the sexual system of chickens is arranged. The very process of fertilization of eggs in this bird is quite natural and common. That is, after the spermatozoa get into the cloaca, they begin to move around in search of an egg and, having discovered it, get inside.

Cloaca, used for mating, incidentally serves in chickens also for the removal of waste life. The very sexual system of these birds consists only of internal organs. In chickens it is a groinlike ovary, located in the left part of the peritoneum, in cocks - a pair of yellowish-white testicles with seminal ducts flowing into the cloaca.

Ratio of individuals of different sexes in the herd

Perhaps the question of how the cock fertilizes the chicken, and is important for purely cognitive purposes. However, for the successful breeding of a herd, this knowledge can hardly be too useful. It is much more important to be aware of how many males in the herd must account for a certain number of chickens. After all, how well the ratio of individuals of different sexes is chosen will depend on the quality of egg fertilization, and hence the percentage of hatchability of chickens.

Usually, the owners set up one cockerel for ten hens. At large poultry farms, a ratio of 1 to 20 is often used to obtain an incubation egg . These figures should be guided. Ten individuals - the optimal answer to the question of how many chickens can fertilize the cock. The only thing that can affect the required number of males is the characteristics of this particular breed. If the character of its representatives is active and active, they increase the number of chickens. At the content of calm rocks, on the contrary, more males are introduced.

How to choose a cockerel?

Thus, the ratio in the herd of individuals of different sex has a significant enough impact on the quality of offspring. However, to an even greater extent, the survival and productivity of subsequent generations in the herd depends on the characteristics of the cockerel itself. Of course, you need to choose the manufacturer correctly. As the cock fertilizes the eggs of the chicken, we have figured it out. The process is absolutely natural. That is, spermatozoa simply penetrate into the egg, as a result of which the latter begins to divide. But, of course, for a good fecundity, they must first of all be active and healthy.

It is believed that a good cockerel can choose to be guided not only by its exterior (which, of course, must fully comply with the requirements of the breed), but also paying attention to its behavior. To leave in the herd there is that bird which:

  • Actively suppress attempts to establish the primacy in the herd of any chicken;
  • Loudly sings and with all his appearance shows who is in charge here.

Of course, we should pay attention to how the cock fertilizes the chicken. A good individual mates with the representatives of his "harem" willingly and confidently.

How to make sure that the males do not fight

So, as the cock fertilizes the chicken and how many individuals of the male should be kept in the herd, you now know. The ratio of 1 to 10 usually gives the best results. Thus, if there are a lot of chickens in the herd, of course, males often have to have several. Meanwhile, as is known, because of their activity, these birds are very fond of measuring their strength. And in the fight sometimes cause each other serious damage. How to avoid such trouble? For this, you only need:

  • Choose from the brood not too aggressive individuals.
  • Put a ladder in the middle of the coop. A weak cockerel when attacking a strong one will jump on it, thus avoiding mutilation.

Thus, you now know how the cocks fertilize the chicken. This process, as you can see, is quite natural. Even though there are no external genitalia in these birds as such.
