Nonsense. They aren't that bad, just give them space and some cover. Quail are brush birds and keeping them in bare cages is a sure way to cause trouble, IMO.If I do start this whole quail business, it will just ensure less time on this site as I will have to deal with tiny little cannibals running around trying to scalp each other.
I do have a rat proofed 8x16 unused coop/barn thing I could jam full if I wanted to. That's in addition to the 4x8 garden pen, and the 4x8 rabbit hutch.
