What is the breed?

[Austin P]

Hi, I am new to chickens and bought 17 chickens from our local feed store, 3 of which are Golden Sex links. This is one of the 3 they gave me and it doesn't look anything like the other 2. They are now 6 weeks and I'm wondering if someone could tell me if it is or not.
Thanks,

Maybe a White Plymouth Rock got mixed in the batch?
