Black Chicken with 10 toes

[Sinadrea]

Hello all,
I am wondering if anyone knows what breed this chicken may be or what breed she is mixed with? She has black and yellow legs with 5 toes on each foot. I thought she was an Australorp until I noticed the extra toes, comb, and eye color. I got her as a 'hatchery choice' chick. Thanks all for your help!

Maybe an off color Mystic Onyx? Those have Silkie genes, but usually have dark skin on the face and body. It's the only thing I can think of that sort of/kind of fits.
