1. Body type identification.
In general, male chicks are those with a larger physique, a heavier body, round eyes, a long, pointed beak, and thicker foot shafts.
2. Feather speed identification.
That is, the feathers are born fast and slow to distinguish between male and female. The growth rate of chicken feathers is mainly controlled by a pair of genes on the sex chromosome, so it is inherited by companionship. Using a fast feather rooster (kk) with a slow feather hen (k-), the slow feather of the chick is the male chick (kk), and the fast feather is the female chick (k-), this method is simple and fast, and the accuracy rate is about 99%.
3. Identification.
This method should be carried out within 12 hours after the chick emerges from the shell, pay attention to the coordination of the left and right hand movements when turning the anus, and do not completely open the **, affecting the identification. First of all, it can be observed whether there is a reproductive protrusion, if there is no protrusion, it must be a female chick, if there is a protrusion, there are two possibilities, that is, male chick or female chick. In this case, it is necessary to distinguish according to the tissue morphology of the reproductive protrusions. The outline of the reproductive protrusion of the male chick is obvious and substantial, the foundation is stable, and the surface of the reproductive protrusion is tense and shiny; However, the outline of the reproductive protrusion of the mother chick is not obvious, atrophied, and the surrounding tissues are weak and isolated.
4. Identification of moulting time.
In terms of moulting time, the female chick changes its hair earlier than the male chick, and on the fourth day after hatching, the female chick has new hair on the breast and shoulder tip, while the male chick does not have this phenomenon.
