Emma has pale skin under her feathers, 5 toes, black floppy comb, wattles, and beak. Here is a better picture of her.Agree with Black Australorp. Is the other black all over - beak, skin,legs, comb? How many toes?
There are other black factored Breeds than silkies,
She's a silkie X. I said that because of the crest, feathered shanks, dark skin, body shape and now the five toes confirm it.
