Hmm hopefully he learned his lesson. My bantam Roo strutted up to me when I was sitting in the run one time threatening me. I back handed him across the run and he hasn't done it again
At least your silky is small enough to not be a threat before learning a lesson.

Sigh. Well I was attacked by my first roo today. Something hit me in the calves from behind and I turned, expecting that one of the chickens had accidentally run into me, but there was Cab Calloway, my white silkie roo looking altogether too pleased with himself. So I chased him around and kicked his fluffy little butt.
Everyone is allowed a "mistake" but if they don't learn from them...aggressive roos do not get rehomed and are not put up with here. :/
