My chicks are in a spare room in the house (also where my computer is). It's getting really hot in here and I'm starting to notice that the chicks are panting and pulling their wings away from their bodies. Would it be better to turn off the lamp and keep the door closed to keep in the heat or would it be better to keep the heat lamp on and open the door to let some cooler air in? I don't want the chicks to get a chill since keeping the door open will let the air conditioning in but I don't want them to be miserably hot either. I envision coming in tomorrow morning to 6 little melted puddles containing a few tufts of feathers each.
