Regardless of what they look like, I would let them decide for themselves who has to go. Believe me, I rehomed mine one by one for things like aggressive with the girls, like nasty, flighty, picking fights, etc, till I was down to 2 roos that are brothers, top and bottom of the pecking order, but basically get along, alpha-I can pick him up and kiss his head, he's good to the girls. Ugly Eddie at the bottom, well he's sweet. I have 2 silkie roos and a hen living together. Now its 2 silkie roos, a hen, and 3 Polish chicks living together no problem. In a separate coop. One roo attacks me, but it is more funny than anything. He has a beautiful crow and gets along with the other 2. If that should change, he will be rehomed.
