I can't tell what kind of comb it has.
The only feather legged breeds I see in My Pet Chicken's rare breed assortment are Cochins, Brahmas, and Marans. (well, also Faverolles and Sultans, but it's definitely not those).
That is not a Marans color. It's legs are too sparsely feathered to be a Cochin. That would leave Brahma, except the only 2 Brahmas they list are Buff and Light, and it's neither one of those.
So I'm stumped.
