others can give a LOT more advice than I can. but I have an 8x8 coop that is raised up 24" (on legs) I use a step ladder to get in it and it is tall enough to stand up and walk around in. I LOVE IT!!!!!!!!! The chickens can go under it which is great for the shade as well (it has HWC all around the bottom of it so it is closed off and part of the run area.
