I purchased 3 black "pullets" from an auction early last fall and I was told they are all the same breed but I feel like the two roosters could be Cornish cross and the hen could be an austalorp? The hen has black ears, single comb, black/slate legs. Roosters have pea combs, more vibrant colours than I was able to capture in the pics and have mostly yellow legs with some black on the front. Both roosters look the same. All of them have great temperment.
