I have just one lone hen right now, and she is molting, and it's going to dip to 15 degrees here tomorrow night and the next. My coop isn't built for such cold weather, since I live in Georgia. I wouldn't worry much except her head is bare and she doesn't have her fully downy coat, and she doesn't have another chicken to warm up with. Sooo, I was thinking of putting a heating pad on low under the straw in the coop, just to keep it from getting too cold in there. I'm a little worried about a fire hazard with a light or heater, but I thought maybe a heating pad would be safe. I have one that stays on 24 hours. What do you think? Bad idea?
