I think you have a Black Ameraucana its all black and you can see the white tipped wings on the right side shot of the black one. Thats a classic black Am growth pattern to all Black Am Chicks. And most blacks in general i beleive get white tipped wings as chicks. My Black Cochins did also.. Also its way way to young to be looking at the leg color on the black one. they will start this way and fill out all the same color if its a Black AM
I believe, correct me if I'm wrong, SpeckledHills comment about the leg color is based off the appearance that this chick has yellow skin. AMs do have toe color that will fill in as the chicks grow, but the tips should be white. Not yellow. Yellow skin is not an AM trait, and it would not be too early to determine that.
