We have four chickens and one duck, and right now, they currently live in a playhouse at night, and free range all day. I plan on putting a super huge dog crate in my wooden shed with a heat light and the shed has a tarp with three windows. I was going to keep the chickens and duck in the dog crate, but let the chickens out during the day when it's not too bad out. Should I even let them out at all? Is it okay to keep the duck in? Should I let him run around, too? Thanks in advance.
