The feeding density of chickens in chicken battery cages refers to the number of chicks per square meter of ground or cage floor area in the brooding house. The feeding density is closely related to the growth and development of chicks. The density of the flock is too large, crowded food, water and food, uneven hunger and satiety, chicks grow slowly and irregularly. If the density is too high, the air in the brooder house will be polluted, the carbon dioxide content will increase, the ammonia smell will be strong, and the sanitary environment will be poor. The density of the flock is too small. Although the chicks are well developed and the survival rate is higher, the house utilization rate is reduced, it is not easy to keep the heat, and the cost of brooding increases, which is not economically feasible.

Determining the appropriate feeding density should be flexibly grasped according to the specific conditions such as breed, season, chicken house structure, ventilation conditions and feeding conditions. Generally speaking, the feeding density of white-shell laying hen breeds is higher than that of brown-shell laying hens, and it can raise 3-5 more per square meter. Weak chicks can't stand crowding, and the feeding density is lower than that of strong chicks. If the ventilation of the chicken house is not good, consider reducing the feeding density. Winter and early spring are cold and dry, and the density can be higher. In summer and autumn, there is much rain, the temperature is high, and the density can be appropriately lower.

When using chicken cages to raise chickens in the Middle East, the size of the brooding group depends on the conditions of the equipment and the purpose of rearing. The number of each group should not be too much, the feeding effect of small groups is better, but the number of feeding is too small, the cost performance is not high. For brooding of commercial layer hens, large groups can be adopted, with each group ranging from 1,000 to 2,000, and even up to 3,000 to 5,000. However, it is still better to raise small breeds, usually 400 to 500 per group. The mother chicks are raised in groups.
