My cock of the walk, Rusty, is a big beautiful Welsummer which I raised from a 2 day chick. He gives imposing cockerels the bum's rush, is an insatiable Don Juan who treats the hens quite good. He survived attack from coyotes last year, and a stray dog this year, so one would think he would be reclusive or aggressive. He is very gentle around people and will come over when I handle the hens, but never acts aggressive. He will readily eat out of hand with the hens but objects at first when I pick him up. So, I handle him at night when he is on the roost and less likely to bolt. Mrs. Welsummer, the only other of the breed, is not so eager to be around people.
I also read that Buff Orps are docile, which is why I have 4 hens. I don't think you have much to worry about with an Orp rooster.
The finest rooster I've had, Blue Boy was a Splash Blue Red Laced Wyandotte. He was gorgeous, robust, gentle, easy to pick up and very attentive to his 2 hens. I did isolate him from Rusty. the stray dog got him.
I have a young Bresse rooster, Isolated from Rusty, which is just starting to breed. The breed is docile but skittish.
A rooster I had to get rid of due to aggression was Trump, an Indian Red Jungle Fowl. He strutted around, tried to bully humans and was abusive to the hens. He was impeached then sent away to another farm's maximum security facility.
