I keep my buttons indoors. Here are a few things i've learned:
-feed the highest quality organic food you can find, and supplement their diet with spirulina and wheat grass powder if you can. The reason for this is that commercial game bird crumbles make for poo that is eye-wateringly stinky. The blue-green algae and grass powder contain chlorophyll which is a good de-funking agent.
-corn cob husk bedding is absorbent and inexpensive, as well as gentle on the birds' feet.
-provide an artificial light source for 12-14 hours per day and preferably one that provides UVB light. Otherwise, your birds will stop laying and may end up with metabolic bone disorders. If you don't want to shell out for the special light (they are available at most pet stores, but somewhat expensive) then you'll need to put your birds outside for a few hours every week or so and allow them to soak up the sun.
-clipping your button quail's wings on one side will prevent them from flying and they'll eventually "boink" less often.
-female buttons can happily live in groups without a male. They'll still lay delicious eggs, though the eggs won't be fertile.
-if you offer a sand bath (which you should!) choose a cage with high plastic sides like a deep guinea pig or rabbit cage. That sand flies everywhere!!
-mine enjoy an empty fish oil capsule as a toy. I poked a hole in the capsule and squeezed out the oil over their food, and the leftover capsule is about the size of a button quail football. The girls love to chase each other and play tug of war for it.
-my tuxedo and golden pearl girls seem to lay smaller eggs and lay less often than my "wild type" girls. This may not be true of all button quail, and could have something to do with the breeding practices of an individual breeder. Hard to say, as i don't know anyone else who has multiple colors and monitors their eggs production that closely!
Regardless of which species of quail you choose, i hope you get as much delight from them as i've had. I honestly think that bringing quail into my life was one of the wisest decisions i've ever made!
