I have 3 Orpingtons. We are in a cold snap but so far I have not used any supplemental heat (and I usually don’t). I have an attached run that is covered in 20 ml clear vinyl. It is supposed to get down to 14 tomorrow night, 11 Sunday night and 7 Monday night and then up to 16 Tuesday and about those night time temps at least through next Saturday. I have a clamp on brooder lamp that has a 120v 250 w red bulb and a cage over the light. The coop is pretty good size (I can stand up in it). Is it ok do y’all think to use it during these next few very cold nights. It won’t keep the chickens awake or stress them out will it? The crazy things sleep in the nesting box which juts out from the coop or I wouldn’t worry about it as much
