Just brought home 3 chicks (Barred Red, Rhode Island Red and Ameraucana). At first they were eating and now the are all huddled away from the light. Temperature reading in the hottest part of the brooder (directly under the lamp) is 90 degree Fahrenheit. Is it normal for them to be inactive when you first get them home? At first they were eating for the first 5 minutes and just stopped after that and lay down with their eyes close and breathing kind of heavy.
