1. According to the reproductive process to identify. This method is best carried out within 2 to 12 hours after the hatching of the chicks, and no more than 24 hours at the latest. Otherwise, the reproductive processes will shrink and the identification will be difficult. Method of operation: When the fluff is dry after the chick is hatched, hold it in the hand to eliminate the feces, sandwich the head between the middle finger and the ring finger, and fix the thumb over the anus, gently press the anus next to the thumb and index finger with his right hand. The anus is opened slightly. Under bright light, if there is a small granular penis protrusion, it is a male chick. The female chicken is not protruding. Accuracy can reach more than 85%. 2. According to the body type to identify. The body is larger, the body is heavier, the eyes are round, the pods are long and sharp, and the thicker feet are male chicks. In addition, when the chicks are 14 days old, if the body is longer and heavier, the legs are taller, and the lengths of the second and fourth toes are not the same, they can be judged as male: If the body is relatively round, the legs Short, but the length of the second toe is the same as the length of the fourth toe. 3. According to the chick's anal sphincter contraction to identify. Males and females are generally more developed than females, and their contractility is also stronger. Therefore, on the day of hatching of the chick, hold the chick in the palm of your hand and observe the contraction of the anus. If the anus flashes for a while, stop for a while and then flicker. The number of contractions of the anus is less and slower. It is female: If If the anus contracts quickly and vigorously, it is a male chick. 4. Differences in villi's renewal and feather growth shape. Normal females are younger than males. New hair grows on the chest and shoulders of female chicks on the 4th day after hatching. This is not the case for male chicks. At 15 days of age, female chicks' wings and tail feathers grew rapidly and their wings were round. However, the male chicks were very short-winged and pointed at this time. The tail feathers were completely absent.
