None should really. But some have had coturnix in with chickens...but the chickens will hurt them I can almost bet it. I wouldnt put any quail in that sort of situation it's asking for trouble.
You can have button quail in with perching birds.
You can have coturnix quail in with pigeons, but only if the aviary is big enough.
So what would you do? Just take the chicks away once they hatch? I have a hen right now that wants to go broody again (part silkie, go figure!), And my dad said I should put the button eggs I just got under her. I think she can just keep sqwaucking about her golf ball!
and i dunno if you raise buttons or not do ya? My button quails egg shells are not thin at all they are very thick and strong stronger than my coturnix quails eggs for sure.
"They are often kept as ornamental or pet chickens by backyard keepers and in zoos, and are also often used to incubate and raise the offspring of other poultry (including waterfowl like ducks and geese) and game birds such as quail and pheasants.[7]"
I'm trying to find you proof that that's how the chinese used to incubate their quail eggs once I do i'l'l surely post it here
here we go:
"Because of their gentle and docile nature, they make wonderful pets and adapt quickly to attention and handling by people. Their tendencies towards broodiness or setting are unsurpassed and Silkie hens will hatch and raise most any kind of poultry or game fowl. Many breeders of quail or pheasant who prefer to hatch naturally as opposed to an incubator will keep a flock of Silkie hens for this purpose."
