I currently have Mouse and her chicks indoors as part of a deal between my mother and I. The deal was that I could get the chicks if I kept them indoors until they were old enough to go out. I know that Mouse would keep them warm but we'll be having rain for another week before getting sunshine again. What temperature can they be out in? Asking as Mouse may need to stretch her legs as she won't move as much in the brooder cage that they're in despite having enough room to.
