I have some blue/black/splash Ameracaunas that are 12 weeks old. Some of them have the muffs and tufts and some do not. Should I still use the ones without the muffs for breeding or is it a flaw. I thought they should all have muffs and beards. They came from a very reputable breeder so I know they are good stock, but not sure if I should sell the ones without the tufts and just keep the others.
