No, all roosters do not become mean. It's an individual personality issue. It also depends on how the humans behave around him. If you or your family are unpredictable, uncertain, fearful, inconsistent, and rough around the flock, when his hormones come in, he will be more apt to want to protect the hens from you.Anyone have any helpful suggestion with RIR rooster. I'm finally convinced my Millie is actually Billie. He's 17 weeks. My hubby wants to call him Wild Bill because he was a wild card meaning could have been either or in the bunch. So wild Bill it is. No crowing yet and no aggression yet. He's not so willing to be held. I don't push the issue but I still want to pick him up just to keep him used to me. My flock of 4 can't free range. I do everything I can to provide foraging activity for them. We are getting ready to make a cattle panel run for them to get them out. I guess what I'm wanting to know is will he eventually become mean under these circumstances? He has 3 girls. I don't think they are over crowded in the 4x8x6 enclosure. Upper level has the nest/roost box. Do all roosters become mean?
Handling him now, establishing that you're dominant, but at the same time, you can be trusted, will make his hormonal adjustment easier. You may still need to re-establish your dominance if he challenges you later, but it shouldn't be an insurmountable hurdle if he trusts you now.
