Ok I raise Jumbo Coturnix Quail. I have 4 pens right now I keep sets of 3 females and 1 male in each. Use hardware cloth and put 1 1"x4" board across the middle so they can get off the wire if they need a break, most of the time they are on the wire. Mine are 3'x2' and 2' tall. They got plenty room even though mine are big. Mine hang off the ground in a metal barn about to my chest/head level. In the wintertime I use a heat lamps to keep water thawed. I have not lost any quail due to cold weather, even though it was bad this year in Virginia. I would probly keep Button Quail in a fish tank. They are small and easy to handle inside. My Jumbo Coturnix are like soft balls at full size, if not larger.
