Guess the breed?!

[Countrylovexx]

Hey guys! Just wondering what your best guess of breed this guy could be. He came from a mixed flocked of: Buff and Lavender Orpington, Americauna, Black Australorp, Speckled Sussex , Barred and Columbian Rock and Wyandottes.
He did have a yellow dot on his head as a chick.

The yellow dot is a trait of Barred Rock right? I was thinking part Barred Rock because of that.

Barred rock/Wyandotte cross.

You sure? Both of those breeds have yellow skin, and this bird has pink shin.
