Nope, the hens have reddish brown eyes, similar to the Roo's eye color. I would say that the color is closer to reddish brown than to orange or yellowish brown. As I have previously mentioned, the pictures are not accuratley portraying the true colors of these chickens. For example, the hens all have really decent coloring on their hackles, but in these pics they look solid black. Also, as to the shank color, I would use "medium gray" to describe the skin color. It's really hard to see because the hens have very heavily feathered shanks. The outsides of their shanks and toes are just about entirely covered in feathers.
As far as any Black Marans in the background, I have to say "not that I know of". These pictured birds are third generatiuon away from what I started with. I do have some blue copper hens in the pen, and I have hatched over 300 chicks from this pool. I have never seen a black, wheaten, "sport", or anything but a Blue or Black Copper ever pop out. I occasionally get a poorly colored one, or a poor developer, but my results have been good for the most part.
If weather permits tomorrow, I'll try to shoot some better, close-up pictures of the eyes and shanks. I think I'm just having lighting issues and can probably adjust the settings on the camera to compensate.
I certainly do appreciate your interest and opinions. You are well respected in the Marans community, and have been at this a lot longer than I have. I'm not in the egg selling business, and I may never even exhibit these birds. I just want a flock of BCM's that I enjoy looking at, and my goal is to get them as close to the French standard as I can.
