It's a cultural thing I think. The northern spheres think snow & ice. We think heat, heat & more heat. My girls would line up along the verandah & face into the sea breeze all year round. It rarely got cold enough for them. I've had half a dozen all winter trying to roost outside in weather I don't want to be out in!Thanks mate! I think so too. So far the hens have survived some brutally hot weather and the coop plays its part in that success.
