what breed are these chickens?

I got them from Murray Mcmurray hatchery as a specialty breed. I wanted to know what breed are they.

First picture is Sex link rooster
Second one I am going to say white rock but that is only a guess

First bird is a Red Sex-link rooster. Second bird is probably a White Rock.
