It really just depends on the individual bird. Most of mine are very laid back and sweet, but I did re-home one for being testy with me. I now have another young cockerel who seems to think he can bully me. Really?? I just pick him up and carrying him around for awhile, then sit down with him to have a talk. He is changing his mind. You can get nasty roos in any breed, and if they are "man fighters", it is best not to breed them, as they do have the tendency to pass that attitude on. On the other hand, even the meanest Silkie roo hasn't got enough size to back up his threats, it's just more of a PIA than anything! Now with my other breed, with 12lb. roosters, that's another story!
