The carrying only works for mating dominance issues, your fella has just plain old dominance issues probably due to his age and hormones. The best advice i can give is seperate him from the ladies so he can "grow" without the need to defend his turf. He may mellow out during this time but if he doesn't it's probably time to find a roo more suited to your flock.
