I have a coturnix quail cage setup that can hold a lot of birds. It has two metal poop trays, two feed tray, and water cups for both levels. It works really nice as an inside a garage setup or could be fit into an outdoor setup as well. It is a Wynola ranch cage. I think I kept 25-30 birds in this one winter in my garage when it was really cold. They kept laying all through the cold. I've gotten out of the quail business.
