Birds are fed. Those that want to be inside are inside and the rest are roosting outside on top of a shelter. None of the pheasants have chosen to seek the available shelter and the turkeys and guineas and peacocks will roost outside even if it is sleeting. A few years ago one of the neighbors cautioned me not to allow the turkeys to roost on the metal pole at the top of the chain link fence, for fear of their feet freezing to the metal when it is wet. The turkeys actually sit on their feet and cover them with their body, so none have ever frozen to the metal. The only bird that ever froze to death got upside down in a tree and apparently couldn't get its leg untangled from the branch.
