Mine are Bobwhites, but I wanted to give them escape/hiding routes in case something got into their aviary. I wound up using an old rado/tv cabinet, putting a couple of holes in the wall of one storage section, and taking the back off completely. The front speaker grill is now a clear plexi pane with a wire floor and their dust bath. A branch leads up to the tv section, which is now a steel grate, and that's stuffed with pine shavings. They have two 3" holes to pop through, leading to a cubby hole and another hole through to the lower section. The floor is lined with rubberized cork so it can wash off.
The aviary started life as a crate furniture style sofa, with a half a door panel hinged onto the bottom as a clean out hatch. It has a human sized door, a small hinged screened door for tossing in scraps, and a bigger hatch toward the rear for adding in branches and trimmings. The floor of the aviary is an old raised garden bed full of compost, forked over and then heavily layered with dry leaves and pine shavings.
