Mystery chicken?

[Emery Mills]

I got a bunch of random hatching eggs in the incubator that a lady gave me.
This one just hatched and I was curious on the breed? Solid black, austrolaurp? Jersey Giant? Does anyone know what it is? Has black legs also!

given the varicolored eggs in the incubator, my guess is that it is a crossbred of some sort.
