I know this is a topic of hot debate but I wanted to heat my coop a bit at night. It gets cold here but then there are times like the last few nights where it has gotten into the low 20's. My California chickens aren't used to that! Plus I have some youngsters in there in a rabbit hutch under a 60 watt ceramic lamp that wasn't even keeping them warm enough. So I got it yesterday after a 2 and a half week wait. I installed it by screwing in four screws and turned it on at 6:30 p.m. I went down to the coop at 10:30 and although it was still cold in there it was definitely warmer than it has been. I have one of the on at 35 degree off at 45 degree outlets that I will use on normal California nights. Here's what it looks like. No fan and it is very warm but not hot to the touch. For those with fancy coops it can be painted to match your decor. I don't have to worry about that. I let my girls decorate their own space and this is what they came up with.
