I've only had my sweeties since mid-July and am afraid they will freeze as the temps drop - help! I live in north-eastern Canada where the temps can drop to -30C sometimes in the mid winter (that's about -20F), sometimes even worse if the wind blows fierce. We get tons of snow as early as November some years! I have Isa Browns, some Rhode Island Red mixes and three silkies - those are the ones I'm afraid for since I have heard they don't survive the cold very well? My coop is about 12 x 12, it's very old and creaky but partially insulated and I am working on putting flextherm boards on the inner walls. The ceiling has some old fiberglass wrapped in plastic and there is a plywood floor, which I cover in bedding. There are two old crappy windows, the trap to the outside coop (not insulated) and the entrance door, poorly insulated with styrofoam. We inherited the coop when we moved here 3 months ago... the former owners didn't do much with it Should I use a heating lamp? Put hay on the floor with the bedding? I don't want the water or the girls to freeze but I don't want to risk a fire or run huge electricity bills either! I'm also thinking they'll get cabin fever if not allowed outside, they looove their time in the sun - if some hens will tolerate the cold but not others, how should that be managed? I don't want the coop to be drafty so that the silkies get ill... HELP!!
