okay, so i have five pullets, mostly feathered, around five weeks old. i have them in the bathroom in a Rubbermaid without a heat-lamp since that's the warmest room and they aren't huddling up. The thing is, they keep jumping out and are getting too big for the Rubbermaid, the third (gradually bigger) container i have put them in. the dilemma is that the temps at night are mid thirties and the highs here are in the mid sixties to seventies. there's at least three inches of bedding in the enclosed nesting and sleeping area in the coop they have yet to be in but i'm afraid they will freeze...buut, if they keep escaping, i'm afraid they might get hurt or lost or find something i missed and eat it. any suggestions would be nice, thank you for your time!
