It's going to be colder then it's been, about -10, tonight. Does anyone who doesn't heat regularly heat occasionally? Will it mess up their acclimatization? Reasons I'm considering it: There are only three of them in a big coop so there isn't a ton of body heat The coop is not warmer then outside by much, if at all (is this because I have so much "ventilation" - basically the top foot of the coop is hardware cloth but it's well above the roost) I haven't put plastic over the windows and there are five big windows right at roosting level (they are closed but not sure if they draft) Last night I stayed up until 1am worrying about them and I need sleep Given all the ventation condensation won't be a problem Ok, opinions? Yes I know we talk about this ad nauseum but my kids will kill me if I hurt the chickens and it's our first winter and did I mention there are only three?
