to be to standard for showing yes, to be a back yard phoenix , no they dont, look at the onagadori forum website, many of those breeders have off colored legs in their birds. It's a common problem with American Phoenix, as over the decades, so many people have played with them with crossing to other breeds, that on occation, you will get a throw back to to one of those yellow legged birds, again, this disqualifies it for showing, but not from being what it is, a phoenix.
