This is my American Serama rooster Percy. Was trying to get a decent picture of him but he ended up giving the evil eye to one of those big flying beetles that was buzzing around up above.
You have to think, Phoenix were accepted to the APA in 1965 and although Moderns were used in developing the breed that was a long time ago.
When trying to improve upon established breeds that's where selective breeding comes in. Find stock with the desired traits and build your breeding plan...
