Identification of male and female chicks

<

According to the reproductive process to identify this method is best carried out after hatching chicks 2 to 12 hours, at the latest not more than 24 hours, or shrinking reproductive processes, identification is more difficult. Method of operation: After the chicks are out of the shell, when the fluff dryness can stand, hold it in the hands to eliminate the feces, sandwich the chick's head with the middle finger and ring finger, and fix the anus with the thumb, gently press the anus with the right thumb and index finger. Next, make the anus open slightly. If you see protrusions (penis) such as rice grains, it is a male chick. There is no or only residual marks on the mother and chicks. You can also use your finger to press the anus. If you feel that there are granules or rapeseed size protruding, it is a male chick, otherwise it is a female chick.

According to the size of the body to identify larger, heavier body, eyes round, long and sharp, long thick stems are male. In addition, when the chicks were compared after 14 days of age, if the body is longer and heavier, the legs are higher, and the length of the second and fourth toes are not the same, they can be judged as males; if the body is relatively round, the legs are Short, but the length of the second toe and the fourth toe is the mother.

According to the contraction of the chick anal sphincter to identify the common sphincter anus sphincter is more developed than the mother, the contractility is also strong. Therefore, on the day of hatching chicks, hold the chicks in their palms and observe the contraction of the anus. If the anus flashes for a while, stop for a while and then flicker for a while. The anus shrinks slowly and is a young female; if the anus shrinks Fast and powerful, it is a male chick.

The difference between the fluff regeneration and the shape of the feather growth is that the normal mother and chick are earlier than the male and the new hair. On the fourth day after hatching, new hair grows on the chest and shoulders of the mother and chick. The male does not have this phenomenon. . At the age of 15 days, the wing feathers and tail feathers of the mother and chick grow rapidly, and their wing feathers are round; while the wing feathers of the male chick are very short and sharp, and the tail feathers are completely absent.
