How high is to high? What is to low? the newbies want to know! Oh, and what kind of slope should I be aiming for in a ramp for them? I'm planning building a coop from scratch, with a row of nesting boxes topped by a poo tray and roost. I plan on getting full sized hens, hopefully austrailorps. How high can i expect them to jump into the nesting boxes or to get on a roost?
