Is there a hard and fast temperature rule for new chicks? Am new to chicken motherhood and mine seem to be fine at slightly lower temps. They are not pooling in the corners to get away, nor piling in the middle to get right under the light. I have only had them since Monday. I check the temp a number of times a day in the box to adjust for the ambient temp and have tried my best to keep at 90-95, but they seem just as happy when it has gone down towards 85, thou didn't let it stay at that. Learning daily. I love them already.
