In South Tx we are 65 degrees at night, and 85+ during the day. Brooder box is 4' long, and 3' tall x 3' wide. I have a red light mounted at the very top of the box. Question is that are my chicks getting too hot during the day? I have 25 in there, and almost 2 weeks old. I'm not home during the day. I noticed when I got home today that they were all on one side of the brooder to escape that heat, but I'm not brave enough to unplug that light when I leave to goto work. I think the nip in the air in the mornings would get them. Should I get a timer for this red light?
