Hi everyone! My chicks are 11 days old and our temp out here in Missouri has been hot and humid, in the high 80's or low 90's some days. The chicks are in my house right now where the temp is about 75-80 in the back of house where I'm keeping them...Do they still need a brooder lamp on all day? or at all? Thanks. I did keep it off one evening when it was pretty warm and humid even after sundown and they were sleeping pretty spread out, all over the brooder, i didn't see any huddled next to one another as you typically do when they're cold.
