This is my hen's first winter! I am a bit nervous about them. I have a coop for the 6 of them, but it is under shade from my house. I cannot move the coop and it seems a bit cooler in the shade. It is getting pretty cold, I don't think I could put a heater lamp inside because that would be an extreme fire hazard, I considered putting it outside during the morning. The main question is, is should I keep them inside? I have been keeping them in for at least 3 weeks, and read they could get ammonia from staying in, but wouldn't it be way too cold outside? I just fear they will die and I don't want that.. * I feed them plenty and also give them a lot of corn to keep them warm at night with all the digestion and give them very warm water. Should I be cleaning them regularly? I heard that it keeps them warm if you don't, but I don't want them to suffocate inside there... I would greatly appreciate some tips and help! Thank you very much..
