I know there have been many posts on the use of red heat lamps, but I have not yet found a good answer for my question. I just put a 250 watt red light in the coop and it's been really cold the last couple of nights (below 0 F), so i've had it on. My chickens do not seem to be sleeping like normal- when i go to check on them, they seem much more alert than normal. usually when i go in there they are pretty comatose, but when the light's on they are roosting and calm, but awake. Or could it be the cold?
