I have quail.... japanese
I keep them just for eggs & the "novelty" factor.
they are also quite easy to raise for meat as they mature quite quickly.
if you incubate, they hatch approx 18 days & I found the fertility really high from our original 7.
as they are so small, make sure everything is really secure & be aware that they can sometimes be quite "flighty" and determined to escape!
a rabbit hutch is great.
keep it clean, as they can quickly develop balls of muck round their feet and can damage the claws or toes.
I feed mine layers pellets & corn, cut maize
you can feed them on game bird feed or some companies now make quail feed, but it can be hard to source.
you could grind up the pellets / chick crumbs etc, but mine have always managed fine.
they are sexually mature at about 5 weeks, yes, 5 weeks so be ready to sex & separate as necessary.
if you have regular coloured japs for example, they are differently coloured. or "vent" sexing is quite easy as his is domed outwards & produces a foam, and hers is more inverted.
hope this helps,
feel free to ask as many questions as you need.
