Hello from beautiful South Bruce Peninsula Ontario! We started our flock in August and they have owned my heart since. I absolutely love owning chickens and am learning lots! But one thing I am stumped on is the issue of heat. We have very cold winters up here, I have no idea how cold is too cold for our birds. Our coop is an old gutted camping trailer, converted and full of roosts and nesting boxes. Looking for any advice or personal experiences to assist in deciding what we should do, thanks so much!
