My Orps are especially nice. I have 3 Orp roos (one buff, one black and one splash) and they are really docile. Salmon Faverolles are really laid back too.
My Orps, Brahmas, Wyandottes have been great. I never keep a mean roo. My chantecler cockerels have always been sort of neurotic and flighty. My std Cochins were always very docile.
