I've been seeing a lot of posts lately on breeding hybrid quail, and I decided to just put this out there. In my opinion, hybrids should not be bred unless you have a clear scientific reason to do so. They're hard to breed, and often you'll end up with a lot of dead quail. For example, when trying to make a coturnix and a bobwhite breed, the bobwhite will probably kill the coturnix. Keep in mind that bobs are kept in pairs and coturnix are kept in harems! Plus, bobwhites take a lot longer to mature. I also saw someone mention they wanted to breed a female button to a coturnix male. The size difference is a huge issue, not to mention buttons are in the Turnicidae family as opposed to the Phasianidae family. Even if you do manage to breed a hybrid quail (which is highly unlikely and not a good idea), it may be very fragile, may be infertile and may have the wrong characteristics entirely. Unless you have a clear scientific reason, why do something so risky? Curiosity killed the cat (or, in this case, quail). With all the quail species available, there's no reason to make a new one.
