I have one 15wo black pullet from McMurray hatchery that came in a variety of hens. I've identified all but her. I'm guessing she's an australorp. She is iridescent with a green and purple sheen on her, and she's beautiful. Her facial skin/comb/wattles all are still outgrowing the black they originally were, so they all look almost purple. Her ears still have quite a bit of black, but I think what is starting to show through is pink, not white. It's hard to tell with all the black still on them. The bottoms of her feet have no yellow - they are mostly black, with a little bit of whitish color showing through. What's throwing me is her build and feathering. Her size and shape are identical to the pearl white leghorn. She's more tightly feathered than the barred plymouth rocks and wyandotte, and appears much more slight of build. Her tail is longer, like the leghorns, but her comb and wattles are still small like the barred rocks. If she was an australorp, wouldn't she be more fluffy looking like the American breed girls? Could her earlobes be white under the black, or would they be all white by now if they were going to be white?
