Thanks guys for the input. I was going to do them 4'x4: because I got my hands on a bunch of 4'x4' cubes made out of Teflon. I was gonna just leave them that size but wont be a problem to cut them in half and put a ply wood back on each side.
I'm new to quail and I'm going to start building my cage this weekend. I'm gonna start with a few coturnix quail. The cage base will be 4'x4' base with 2 or 3 story's tall. I've been reading on a lot of builds and get different answers to a few questions I have. Maybe you guys cab help me out...
