Can anyone tell me what my mystery chick from McMurray might be? It came in with my Cornish X pullets 5 weeks ago. I am guessing Austrolop or Jersey Giant. It has a single comb and is light on the bottom of its feet. I know that the "mystery" chicks are usually males, but I am really hoping for a pullet. It does not have the thick legs or stance that make me think it's a cockerel.
