I'm concerned about me chickens getting cold and told my husband I want to put a space heater in the coop. He says they will be fine, he has seen chicken when he was little walking around on snow. He says they will keep each other warm. But Sam does not get near the other chickens, they all sleep in the coop at night and he stays in the pen on the latter. He is very anti social. What are yawl planning for this winter?
