All my chickens are pets and I don’t cull roosters (I just can’t bring myself to do it. Sorry if it’s not the way most chicken keepers work, but I’m not a typical chicken keeper).If you had an aggressive rooster in the past, you should have culled him. Some roosters are ornery, some are down right evil and need culled. some are big sweethearts.
act like you're the boss because you are. People who are constantly babying their chickens, end up with one's that don't respect them.
