I do not have button quail, but I have a friend who does. I found this cage on CL, and would like to know if it would work for them, or if the slats would be too big for their feet. I'd ask her, but I'm not sure if I want to keep it for myself since it is a nice cage.
(If you're reading this, pretend to be surprised if I turn up at your house with it, lol)
