It's going to be -7 degrees tonight. I have 4 bantams in a 6 x 3 coop, raised off the ground. Will they be ok? 3 EEs and 1 Cochin. I have a calibrated hygrometer in the coop and there is no problem there. They've been fine down to 4 degrees already. I have ordered a coop heat plate from Amazon, it'll be here Saturday. So I'll at least have some heat for the -15 night coming up next week. I could put a heating pad down for them to stand on if they want. Just thinking of when they were little and stood on the top of the MHP. We don't get these kind of temps very often at all so that's why I'm not prepared.
