My rooster is about 6 months old, he's a barred rock and he's a big guy. 2 weeks ago I picked a broody hen off of her egg pile and rooster didn't like that, the fight was on, I kicked him twice to keep him away from my body before running into the house, 30 minutes later I went to go feed them treats and everything was fine. A week later my dad was home and walking to get some fire wood and he passed the rooster, then walked 30 more feet to the wood pile only to get nailed in the back of his calf(so obviously it waited until he turned his back and chased him down). The rooster didn't apply the spurs and there was no broken skin or bruising, but the rooster did get thwacked with a shovel until he chilled out. Well just today I went and let them out to free range, I go in and grab the eggs out of the nesting boxes and I go to leave and I'm met by my rooster. I try to walk one way he goes that way, I walk another he goes back, in an aggressive stance. I get ready to give him the kickball treatment and all the hens come running over. He seems to have lost his train of thought and he went chasing one of the hens around trying to mate with her. I've heard people do things like pick their rooster up and hold them upside down, but I think before I could do that he would put a bunch of holes in my arms. I can understand the first attack, taking the hen off her eggs and triggering his instincts, but the last two don't make any sense to me. Could it be that I was harvesting the eggs from the nesting boxes? Will roosters calm down as they get older? I don't want to kill him, it was out of the question, but now I'm starting to entertain the idea. He might become dinner if he doesn't learn to respect me and my guests. Thanks for any suggestions.
