Yes, I would agree with the above. That "dance" is about dominance. And it's 100% normal. Mine did the same thing at the same age - a frizzle. He now dances, then attacks my leg and draws blood. It sucks when they turn out that way. Not all roos are the same - I have one that is sweet as pie to me, only "dances" and attacks my large dog, but no others. Also, this "show" is about trying to mate. I see my roo's dancing before they hop on a hen and mate - they latch on with their beak on their neck, and can pull out feathers at times. It's pretty brutal. And they don't stop quickly. I wish they could be neutered.
