Cooling chicks is a necessary link in chicken breeding. Cooling is to stop artificial heating and let chicks resist the influence of external low temperature. This process is a very painful process for chicks, so this opportunity must be grasped.

The temperature of the brooding house is generally controlled at 0-65438+33-35℃ at the age of 0 weeks, and then it will drop by 2-3℃ every week, and it will not be thawed until the age of 4 weeks. The thawing time is 25 days in summer and 30 days in winter.
