First, the identification of newborn chicks
1. Out of shell within 24 hours. At present, the use of anus to identify sex is usually used for newborn chicks within 24 hours of hatching, and the accuracy rate can be as high as 99%. In the identification, under the incandescent light of 100W, pinch the carcass with the thumb, forefinger and middle finger of the left hand, and make the young man's head face down, stick it back to the palm of your hand, and hold it gently. Use the right index finger and thumb to gently pry down the cloaca of the chick. If the cloaca's mucous membrane is yellow, there is a small reproductive projection in the center of its lower wall, that is, male; if the cloaca's mucous membrane is light black and no reproductive projection, it is male.
2. Born more than 24 hours. For those who have been born for more than 24 hours, male and female should be identified according to the following characteristics. One male cicada squeaks short Gaolang, and the mother babbling sounds are small. There are red enlarged gonads above the anus of 2 males, and no bulges above the anus of females. 8 pelvic feces often have white foamy attachments, while fecal matter does not have foamy attachments in the feces. The male chest and cheek feathers of 4 males are reddish-brown, while the breasts and cheeks of the females are gray with black spots. 5 male body shape is compact, weight is smaller; female body shape is loose, weight is larger.
Second, the identification of Aberdeen
1.3 weeks old. After the primary moult of the proficient chick, as long as the feathers grow normally, chestnut brown feather-type pupae can generally be identified according to feather shape and stain. The male chest began to grow red-brown chest feathers with occasional black spots. However, this method is less accurate.
2.1 months old. Generally, Aberdeen has basically replaced the permanent feather of the body's body. The chestnut brown feathers of the male pupa start to show auburn in the face, mandible, and throat. The chest feathers are light red. There are even a few black spots on the chestnuts. The main abdomen is pale yellow, and the chest is wider, and some have begun to buzz. The mother's face is yellow, the pigeons and throat are white-gray, and the chest is densely punctuated with many small black spots. Its distribution is like a chicken heart, neat and elegant. The abdomen is grayish, although the color of the breast feathers of a few females resembles that of a male, and the color of the lower jaw and throat can be checked. The mother babbling sounds low and short, like a squeak.
