So I was wondering why there aren't any feather structure mutations in coturnix quail? (eg frizzle, crest, leg feathers, beard ect) I just can't believe there aren't any after all this time in captivity. Also is there a good online guide to coturnix colors? I know about the one here on BYC (Awesome!) but I was hoping there was another one with all the cool colors that they have in Britain. Thoughts?
