Back in the day, when I grew up on the farm and chickens were chickens we never heated the chicken house and they did just fine. I grew up in the Blue Ridge Mtns. The henhouse was well built, relatively free of drafts and they snuggled down, the accumulated body heat kept them warm along with plenty of hay to snuggle in. Snow built up on the roof during the winter and my Dad assured us that it added to the insualtion to keep them warm. They came out during the day and hunkered down at night, I don't ever remember losing one to the cold.
I think that all the worry has come about because we now have put the chickens into the catagory of pets. I have tried to explain to my hubby and son that the word chicken and pet should not be in the same sentence. They don't need a luxury condo, just a well insulated hen house. They don't need a heater (what's next? an air conditioner?)
