Australorps, Jersey Giant, or something else?

This little girl is 8 weeks old. I'm trying to figure out her breed. Her legs are yellow on the back and look like someone took a black sharpie down the front. I have a black Australorp hen ( had a rooster) and the feet don't match. Does anyone have any ideas?

Possible but no feathering on the feet
