4th picture
I found one picture that is very similar to the rooster on the 2nd photo. It is located on the single comb clean legged section on the right side of the page. The photo description is a pair of old english game and I assume that they are not mix breed.
Notice that in the photo, he also has black feathers near his ear lobes, which I think is a beard. It should be longer than that, but it got plucked, when he fights the rooster on the 1st photo.
