Roosters see some people, not all, as threats to "his girls". I suppose some just like to pick fights, but I have no tangible evidence of that. From time to time, not all the time, our roo acts like he's going to attack me and will charge toward me, even jump up in the air with feet coming at me, but he's never done any damage. Why me? We can't figure it out because my bf and I give ALL our birds a LOT of attention. My bf maybe gave him more attention as a juvenile and onward, but for some reason he sees me as a threat or just doesn't really like me.
My bf can do anything with that bird, and the rooster does nothing, almost like he knows that Sam is higher in the order than he is, so he leaves him alone. He can walk right up to him, pick him up, hold him for 20 or 30 minutes and he just sits there content being held.
I wonder if you were able to show that you're dominant over the rooster if that would slow him down at all. I know that Sam kinda forced his will over our rooster's will early on in a gentle "I'm the boss" kinda way. I never did that with him, but maybe that was the key to the roo's behavior today...
