Hi all! Dh and I just realized we need more cages...funny how that happens. We have a current set up of four cages along our side fence, and I am planning on hanging the grow out cages in the chicken run. The girls can pick through the spilled feed and poop, and generally keep things clean. And hopefully not roost on top of the cages and poop on the buns. I might have to cover the tops with something. Anyway, I want the cages to be tall enough to put some resting platforms in and still have enough head room. What height should they be? Oh, the buns are American Chinchilla. Thanks all!!
