My coop has split door on the front and window on the back. During the day I normally open the two top doors for fresh air because it gets stuffy in the summer. Theres not any shade. I had DH cut the doors after we had some wild dogs get in and kill my chickens. Now that it is getting cold should I continue to open the top doors. The wind blow through alot and they kind of act like they don't want to ruffle there fuzzy rumps in the wind. Any advice would be greatly appreciated.
