I don't even have chickens yet but I just ordered an 8' x 8' garden shed which I'm planning on turning into a coop. I live in Brantford Ontario and i'm really curious if I should insulate the coop before getting my birds. I've read a lot of different things on BYC and I'm a little torn. We do get temperatures as low as -20C in the winter. Any suggestions would be appreciated. I'm also curious if anyone can recommend a good supplier of chickens in southern ontario. I'd like various breeds, not sure exactly what yet tho. All tips are welcomed!
