Here in Prince George (middle of BC Canada) we had our first frost last night, and since it's my first winter with chooks I'm wondering about insulation heating etc.
I've got a 6x10 metal single sheet coop, and I'm planning to stack hay bales around up to about 5' high so the ventilation still works!
Not sure about the roof, it should be sturdy enough for snow to stay on and insulate it but it is metal so do I insulate before the snow comes? Not planning on additional light, so if they moult, stop laying then so be it. Anyone else local? We got down to -34 last winter, and it stays under ten below for months over winter.
I have three orpingtons and three marans, all ladies (I think, orpies are too young to call yet!)
