so last week i posted something about heating my coop in winter. i read somewhere that heating your coop can be deadly to my chickens. the article said that if you heat your coop and the electricity happens to go out, the sudden drop in tempurature could kill my chickens. some people sent me some links to my question, but i'm still not sure what to do. so here's a little description of my coop. it is 5ftWX5ftLX5ftH, give a take a few inches. coop is built up against the garage with a unusable human door smack in the middle of coop, but it's cracked open. a few holes in the top of the coop and the chicken door is 2ftWx2ftH. my chickens are a RIR, orpington, small grey cochin, and mixed breed the size of the RIR. they are all around the 15-21 week age. so my questions is will it be safe for me not to heat the coop or is that something i really need to do. after just loosing 5 chickens to my neighbors dog and 1 to unknown causes, i don't think my kids can take loosing anymore chickens. so i don't know what i should do. to heat or not to heat. what do you all do and any suggestions. by the way, i do give them cracked corn every morning and evening, if that helps. thanks in advance.
