I have a rooster and he's about 8 months old. He had an aggressive streak at around 5 or 6 months but after a few weeks he chilled out. He's attacked us but usually it's weak and doesn't even hurt us.. he just jumps up and does the motions, never hits with claws. Well around Thanksgiving I had a friend come over for dinner, big guy, probably 6'4 285 pounds. He told me roosters don't mess with him etc.. well as soon as he turned his back the fight was on. Then just this morning he attacked my other friend, this time he jumped in the air and came feet first. Friend kicked him probably 4 times to keep him away and he just would not stop his advances, he was fearless. I'm getting worried, he can't behave like this but he doesn't much get aggressive with me. Is it because he's familiar with me? Will he eventually get to know my friends?
