I had bought some eggs from a person that were supposed to be a purebred breed but apparently something else got in the coop. I hatched two eggs and both birds are very unique. They are like an oriental gamefowl version of the breed that has completely black legs, head, skin, meat, etc. Turns out I have a rooster - he is like nothing I've ever seen before. He is black skinned and even inside his mouth is a dark gray color where a normal chicken would have pink flesh. It resembles a Malay or a Sumatra. I'd like to perpetuate this unique bird so I'm thinking of crossing him over some khaki sumatra females or a Malay or O Shamo pullet when he matures. I was wanting to know how one goes about developing a new breed though.
