I have eight 5 month old chickens, and I have recently been allowing supervised time with my other flock to allow them to merge eventually. One of these chicks to my dismay was a rooster, he is a crested polish, Sampson. I actually LOVE him, I was literally just talking about how much I liked his personality. He didn't mind being handled, and would race right up to me. Anyways, while all the chickens were out I figured everyone was getting along so I went inside to get a drink. After a few minutes I returned outside, and the stupid rooster went after me - I had to shove him backwards 5-ish times before he angerily walked away. I just kind of shrugged it off, and figure maybe he was in a bad mood - lol! But, then he did the same exact thing later in the day. I'm just really flustered with him, and I don't want him to act like this. I have children that come to my home and love to spend time with my "petting zoo", but a nasty rooster cannot live here. I'm hoping he is maybe just going through some sexual maturation and it will eventually calm down? Is there a way to just asset dominance over him and stop him from attacking?
