1.Feeding system: In the brooding stage, it is advisable to adopt free feeding, and to supply a sufficient number of troughs. Feed is often kept in the trough, allowing chicks to eat ad libitum, so that they are evenly grown. Each chick should have a trough position of 2.5cm and a drinking water position of 1.5cm, and increase the length and height of the trough and sink as the chick grows. Otherwise, it will affect the feeding and drinking of the flock, leading to the growth of the flock. Unbalanced development. At the end of the brooding period, the weight of 50 to 100 chicks should be randomly measured from different parts of the house to determine whether the flock is tidy and whether the body weight meets the standard of the chicken;

2.Flock density: the chickens should be evacuated in time as the chicks grow and develop. group. At the age of 1 to 2 weeks, the cages are less than 60 square meters per square meter, and the average is 30 or less per square meter; 3 to 4 months old, 20 to 30 square meters per square meter, and 20 square meters per square meter. . Using the opportunity of evacuation to separate the strong and weak chicks, and strengthening the care of the weak chicks can improve the survival rate of the brooding. Brooder chicken cages.
