We have to carry a broom around to fend off attacks from our rooster. He protects the hens so well that he protects them from us!
The other day I didn't have my broom. Got my umbrella out of my car, opened it up and simply walked around him by having the umbrella between him and me. He must not see my feet or me. Did not care I was walking by him. Didn't think such a simple thing would work. Only problem is I have to watch all sides in case he slips behind me and attacks the other side of me!
I had a 38 week old cockerel, a White Leghorn, Foghorn, who would rush after my 11 yo son all the time and he once flogged my 9 yo disabled son who was merely walking away from the coop area. My 9 yo daughter was scared to come into the yard when he was loose.
Yes, he was a "good" rooster- finding the girls food, showing them where to lay, protecting and warning them against intruders like the coopers hawk that tried to get my WL pullet, and of course mating any of the girls he pleased. He performed the rooster duties flawlessly.
He was top alpha roo and he knew it. I wasn't attacked by him because every time he came near me I bent forward as if to pick him up. He would rush away and crow. I didn't run from him and I didn't need a stick around him. But I also didn't turn my back on him for long.
The kids knew better then come near Foghorn. I caught my 11yo teasing the cockerel when he was inside the run. Not surprised that Foghorn would tear after him once he was let out to freerange. However my disabled son wasn't teasing him and I couldn't have Foghorn attacking him as he doesn't understand how to protect himself from the rooster.
I needed to weed out the cockerels so Foghorn was rehomed to a cockerel only property where he has established himself as top alpha roo and is happily hunting for bugs without the worries of ladies nearby. But, he is attacking that family's members now instead. thankfully they are adults and can fend him off. I've instructed them how to turn and face him off, they keep choosing to run from him.
So once an aggressive rooster, always an aggressive rooster, it's in his nature. Unless you're prepared to watch your back and the backs of visitors, I'd go ahead and process him and enjoy him that way.
