Doubtful. She's got a pea comb, meaning one or both of her parents would have had to have a pea comb. She also appears to have a thin beard. If one of her parents were one of the two breeds speculated, I'd say she'd be part Australorp. Leghorns have yellow legs and large white ear lobes. Her earlobes are pretty average sized.Could she maybe be a mix of the two breeds?
