There was a separate picture with a different bird that is now gone.
The rooster in the original post has a crest, so it can't be a pure Wyandotte of any variety.
His comb and shape are similar to a Wyandottes. His coloring is similar to a speckled Sussex. And he has a crest, which didn't come from either of those breeds. So probably very mixed parentage.
The sexes usually have different color patterns early in this variety. It's not 100%. In the Hoover's photo the female is on the right and the male is on the left.
With the list the breeder provided, I am guessing he or she gets chicks from a hatchery and resells them. The only thing that really fits your bird is Easter egger. They can lay any color of egg.
If the breeder is actually breeding from his own flocks, then you have some kind of mixed breed...
