Angry rooster

So this is my darling little boy, he was born in October 2025 and has just begun to crow and call out to the chicks when he finds food. So he's pretty young. Now here's the problem, he's starting to peck me without pretty much any warning, he doesn't fluff up his neck feathers or anything. He just walks up to me sometimes and bam, I have a new bruise or wound on my hand. Now heres the thing, he was the only one of 30 chicks we hatched and he imprinted on us because we were the only things he knew as parents before the other chicks after him hatched. I really want him to stop this behaviour because if he continues to attack.. I don't know what to do with him. So I tried to carry him around or hold him on the ground but hes still pecking somehow.. please help. I really don't want this to get worse. :/
