Give him some time to see if he mellows a bit bast the teen period for a rooster. If not, Culling is often the best option. Culling is removing from the flock--sell him or give him to a rooster rescue if Processing is not an option
Welcome to Backyard Chickens! We are glad you joined the flock! BYC is a helpful site providing all the information you need to know about poultry! If you are too squeamish to cull then I'd recommend giving him to someone who might use him in a breeder flock. Hope you enjoy it here as much as we all do!
NEVER a good reason to keep a BAD roo. They saw the meanest roosters make the best soup. Let someone else have him free- he will probably be guest of honor at dinner but, that will keep him from harming any one/thing and not fathering any chicks with his bad attitude.
Hens will lay just as many eggs without a rooster, though the eggs will be infertile.
Hope you find all the information you'd ever need regarding your feathered fowl- and maybe make a few lasting acquaintances along the way!
In regards to that rebel roo...if you're against rehoming or ultimately culling, babying them sometimes works. If you're able to corner him somehow, just pick the brute up and coddle him in front of his ladies. There's nothing more a rooster hates than being shown as wimp in front of the girls. After a bit, he'll start to instinctually avoid you and the corresponding humiliation. It may take awhile and a lot of hated hugs, and it may never pay off, but I've gentled more than one testy boy through this.
But typically once an aggressive roo, always an aggressive roo. You may change his interaction with you, but if he's overbearing with the flock itself, the wisest idea would be to send him off.
