Weird-colored legs!

[austrolover1]

I have a few-week-old chick that is a mix-1/4 Buff Orpington, 1/4 Dominique, and 1/2 Black Austrolorp. Her legs are NEON YELLOW!!! I am rather confused, because BA's have blackish legs and the BO/Dominique have whitish/creamish legs... Can anyone explain this? The Black Austrolorps and the BO/ Dominique roosters are the only chickens in the pen, so they cannot be another breed.

Thankyou. I guess that makes sense. She didn't have yellow legs till recently, though. I will watch the other chicks to see if their legs turn yellow too!
