Glossy Black with green iridescence, with no markings(pic color belies it), comb like a Leghorn, white ear and lays large white eggs every day. I can't find any breed pics anywhere that look like her. I bought more solid black chicks this year hoping for more just like her and got the gold breasted mystery chicks out of them instead! Here is a pic of my Black Australorp (I think). Bought both together as solid black chicks hoping all would be Australorps, but 2 turned out slender with the large comb, and this one is a heavier bodied hen laying a large torpedo shaped brown egg. The color in the pic is poor, she is really jet black with iridescent green, not brownish as the pic seems. In this pic left to right dark chickens: BA chick, black (Leghorn-looking) hen reaching under my BR roo, gold breasted mystery chick back a bit, another BA chick, and forward the BA hen.
