That's the one to get rid of.....'familiarity breeds contempt' can be very true in the chickeneering. Human aggressive males are often the ones who were 'cuddled'.
If this your first flock, might be best to get rid of both.... and maybe get a male with next years chicks.
I may be an exception as I have silkies and raised two of my boys from eggs and the other was mature when I got him... But mine are total marshmallows and I snuggle them on pretty much a daily basis. Heck, Peep-Peep who I raised fully from egg to cockerel even defends me when the toe-biting hen attacks my feet. Though I have set myself as above them in the pecking order and lightly poke them, akin to a mother hen's scolding peck, when they misbehave.
Rooroo, who I didn't raise, used to attack me if I handled his hen and she started flapping about. He doesn't anymore with me, but my dad does get attacked by one or two kicks if he messes with the hens and youngsters when they don't want to be handled. My dad finds it amusing though and doesn't correct it like he should when it happens, so I don't see that changing with him.
Scruff, the youngest was co-brooded with me and Hen-Hen and is a little nippy, but I am getting him out of that habit before it sticks. He doesn't like his legs and feet being touched and I know if he ever has mites or any claw and spur problems, I will have to do it... So I pet his legs and feet and lightly poke him on the head when he pecks me, or 'peck' his beak, a thing I learned from my flock as they interacted as another way to show dominance.
He went from biting hard and occasionally trying to mount my hand, trying to show his own dominance, to doing soft little nips that could barely be felt, to just awkwardly standing there and letting me touch his legs and feet. He still nips, but I am making progress.
He still likes being around me even with me messing with his feet every now and then, as this afternoon when I was sitting out with them, Scruff hopped up on my lap for some fussing... Only to get shoved off by a bossy older hen that also wanted a fussing.
I eventually got the two of them to co-exist on my lap.
