My serama will probably be housed inside and taken out daily to forage and get fresh air, probably in their own run that I can move around. That way I can keep a couple roosters and not worry about noise complaints with their little crows! These are all just plans anyway, sadly I won't be able to set anything in stone for a few more years at the earliest.
I thought some flying birds would be nice with the quail though, since the quail will mostly occupy the floor space of the aviary. I think having some serama hens in there, tiny as they are, would make the floor space a bit more crowded.
I might not even do quail though, I haven't really decided, to be honest.
I'd like to have them as a food source for myself and mostly for my cats (and future dogs) but I couldn't do the killing and processing myself. So, I figured when the time comes, and I've moved into a place in the US, I would ask around/post and see if there is anyone in my area who'd be willing to kill and process quail in return for some of the birds. As in, I raise the birds, give the "butcher" 20 birds and they process them in return for keeping 1/3 or half the processed birds, or somewhere along those lines. That way I don't have to "get my hands dirty" and the surrogate-butcher gets something in return for his/her work! If nobody wants to do it, maybe I'd just keep a few as pets and for the nice quail eggs.
