I am wondering about keeping chickens in the winter. Should I keep them locked in the coop when there is snow on the ground or when it is a certain temperature? Or do I do as in warm months and let them out during the day? I have been keeping them inside the coop but I feel like they really need out of there. I do not have a covered run so there is snow in their yard. They can get under the coop where there is no snow but that doesnt mean they will stay there....sooo?
