In my MMH order, there were supposed to be 3 Black Australorp. The packing slip said they included 1 free extra Black Astralorp. Ok, no problem. Except that now the chicks are 11 days old, and 3 of the black ones are all identical, and very clearly Australorps. But this fourth black one is different - and has feathered legs! The other black ones that are identical have very distinct creamy colored undersides, and definitely no feathers on the legs. They also don't have the white barring on the wings, but have white wing tips. I am sure that I identified who was the mystery chick because it was a single chick unlike any of the others, but now this one is unlike any of the others also. So did they give me TWO mystery chicks?? So what is she/he?
