I have 9 cockerels that are 9.5 weeks old. Over the next two weeks, I need to pick my best two to keep intact for the flock and the rest will get the ol' snipsnip. The one I like best for all the other reasons has a flaw. One of his wattles is smaller than the other. I think it's a battle scar from a pecking-order fight with another cockerel probably several weeks ago now, which is okay; but if it's a deformity, I don't want to breed him. Does this look like a battle scar or a deformity?
