So I received my 5 black copper marans girls yesterday. One had a horrible broken leg and had to be put down, so now I'm down to four. And looking more closely at them, one of them appears to not even be the same. I'm attaching several photos. The three chicks that match the breed photos have yellowish white bellies and throats, yellow feet, and white feathers on the tips of their wings. The fourth is all black with black legs and a grayish white bottom. It does have feathered legs. I'm going to call them tomorrow, but can anyone that has experience with bcm's chime in?
