i have a small coop (the one pictured inside he run). It is 59 x 30. I'll be keeping 4 bantams in it. Was wondering if anyone else uses a smaller coop like this and how you handle winters? Do you keep the coop closed all day when it's freezing out and where do you keep the food inside the coop if so. The coop opens from the top, so I'm guessing hanging the food would not work. I don't know if they would even stay warm enough in this coop. It's a Trixie Natura pre fab coop. Thanks.
