I was just given these roosters about an hour ago and the man didn't know what breed they are. I have 2 other roosters so I'd like to know what they could mixed with so I can sell them for the proper amount. One has, I think, a pea comb and the other has what looks like a buttercup comb. They look like the same breeds except for their combs. Also any guesses on age? I have no clue. The 1st and 3rd pictures are the same one and the 2nd and 4th are the other. They're not really white but more of a yellow color.
