I recently bought a beautiful 5-6 month old Jersey Giant Rooster from a lady in Olympia,WA. He is black with both green and purple sheen's, he sounds like a typical Black JG right? Wrong! He's got feathered feet! I was wondering if his breed is subject to vulture hocks? Is this some kind of genetic mutation? Is he a mix? He looks pure JG except for his feet. I will try to post pics as soon as I can upload them from my camera.
