I'm honestly not sure whether she has any Modern Game in her or not, she looks like she could, but because she isn't standing up it's hard to tell.
I think I see some Silkie in her, because of the black skin and weird mutt comb. So maybe a BB red Modern Game Silkie mix? Whatever she is, she looks really pretty.
Silkies are not the only black skinned breed...what about sumatras? Additionally, there are many breeds that have a copper mantle like that. Anyway, we could use more info. OP, does she have five toes on each foot? That is a dominant trait, and if she was a silkie mix, she should have five toes. Is the egg in the picture from that hen? If not, what color/size egg does she lay? As the others have stated, in order to give you a good idea of what she is, we need to see her standing in a natural pose from the side (if you can include her legs and feet in the picture, that would be helpful). Is she a standard or a bantam?
I don't know much about black skinned breeds, and sumatras may not be truely black skinned, but they do have the ability to show at the very least some very dark purple skin. Especially in the facial area. All I was suggesting is that without more information, we really can't say with any certainty she is a silkie mix.
