How cold is too cold in general for chickens? My wife is worried about our chickens freezing to death. We have a 6x7 coop and have 10 chickens. The water is freezing overnight so I know that it is at least 32 or so here at night lately. The inside of our coop is just stud walls and none of the coops I have seen are insulated do we need to insulate? WIll the chickens be fine? We live in Indiana btw. Does anyone use a heated waterer? How do you keep their water from freezing? I know it might screw up their sleep patterns (if chickens even have those) but can we use the heat lamp from when they were chicks in the coop all day everyday? Will the eggs freeze? Thanks for all your help.
