The body temperature of newly hatched chicks is 3℃ lower than that of adult chicks, and it will take 10 days to reach normal body temperature. In addition, chicks' villi are short and thin, so they can't keep out the cold, so their adaptability to the environment is not strong. Only by artificial heat preservation can chicks grow and develop normally. Chickens aged 1-30 days should be kept warm and kept in a clean and hygienic environment. Chickens over 30 days old have basically full feathers and can be kept warm.

Generally, the body temperature of chickens is between 40.8-4 1.5℃, so they must be raised in a well-ventilated environment with warm winter and cool summer. In addition, chickens have short digestive tract, vigorous metabolism and rapid growth and development. Therefore, it is necessary to feed nutritious and digestible feed to meet the needs.

Other aspects

Chickens, in particular, are vulnerable to harmful microorganisms. Therefore, in addition to cleaning the environment, we should also do a good job in prevention. For example, outsiders are strictly prohibited from entering and leaving the henhouse, the environment and cages should be disinfected, and all kinds of chickens should be injected with various vaccinations regularly.

Chickens are timid, especially chicks, which are easily frightened. The light ones are crowded, the growth and development are blocked, and the heavy ones trample on each other, causing disability and death. Therefore, raising chickens in quiet places, rough management, sudden noise, dog and cat intrusion, catching and so on can all lead to riots and affect the growth of chickens.
