Need to make sure I am reading all the information correctly. I have 1 week old baby chicks. This week the temp was supposedly to be lowered to 90 and I have done that. The chicks are hanging out completely on other side of the brooder box. They are huddled together sleeping and are eating and drinking well and active....no distressed chirping or anything along that line. It appears that the area under the lamp is too warm for them. Should I lower the temp slightly (raise the lamp) perhaps to 85 to allow them to spend more time under the under the heat lamp or just let them spend all their time on the colder side of the brooder. Don't want to keep them too warm.
