Being a newbie myself, I'll be interested in reading the responses. But I was wondering if I read somewhere correctly that it's probably not a great idea to control the temperature too much in case there is a power outage and you don't have an immediate backup? The girls would be more sensitive to the temp change and die?
If that's the case... would a bare lightbulb work in a space that's about 4x6?
I've read about people keeping chickens in Alaska that never heat their coops and never lose a bird. Wonder how they can manage this?
I don't use heat, but then, I don't like in SD!!
I do have large cracks in the floor of my old coop where the wind whips in, so I'm going with the DLM this year to see if this will protect from drafts and even generate a little heat from the organic material and decomposition of the litter. We do get zero weather on occasion here and my chooks haven't had any problems, even with the large combs.
There is a stove pipe hole in the roof of this coop, so these folks obviously heated it with coal or wood in the past. Of course, back then we had much colder winters in this area.
Other folks seem to think a light bulb's heat will help keep things more toasty in the coop.
