Thanks for the input everyone!

I'm still in two minds, though.
I kept parrots as a teenager and always had two or three pair of quail in my aviary. I never noticed any smell and the system worked well. I kept potted spiky shrubs for the quail to hide in as well as a network of PVC pipes. In return, they kept my aviary floors fairly free of waste food and, hence, I had fewer mice invading (except for the Massive Mouse Invasion of 1980, but that was an exception).
My current birds aren't in aviaries, however (not enough space, buggerit!) The Beaks are in a very large cage 2m x 2m x1m and the Lovies are in a flight cage 1.5m x 1m x 70cm, so neither cage is as large a floor area as my old aviaries. Thing is, the amount of food wasted is enough to support a small village for a fortnight! Hubby is
going to make me more no-waste feeders from acrylic, but I'm not sure when. I just figured a couple pair of quail would nom up all the waste for me so I didn't feel so bad about it. As it is, we collect up as much as we can and put it on the roof for the wild birds, who really appreciate it.
I don't recall my earlier quail ever smelling, Mikey, but as Mike 17 said, their feet would get clogged up with poop and I'd be forever cleaning them (a dab of cooking oil helped a lot: the poop won't stick to that). These days, my sense of smell is all but gone, so the problem would not be mine. LOL! Also, the Beakies like to poop in exactly two places in their cage, so it's not as if the poop coverage is all that great. The Beaks also don't spend any time on their floor, which is why I began wondering about quail. I'm not doing it, though, until I've heard of someone who has done it successfully and had advice about it. Quail are great little birds and have a personality all their own (especially the King Quail, my favourites).
I dunno about the Lovies. I know plenty of people who keep quail with them in aviaries, but that's a bit different from a cage with lots fewer places for quail to hide in. Ah well. Still thinkin' about it... I'd be glad of any more opinions if there are any.
Sorry for the long rambling post, but as you can tell, it's my stream of thought.
