Only had chickens for three years but learned something new today! If you do use a red heat lamp please make sure your roo's cannot get beneath it where their feathers will burn!?! Thank God my banty roo and my RIR/BOx roo did not catch on fire and burn up their coop along with my only Silkie roo! I took away the red lamp and replaced it with a cooler white one. Its to keep their water from freezing and in 3 years, this has never happened and Thank God, too, I was on my day off instead of at work or I'd have another story to tell:/
