Wait, if I read this correctly your saying instead of jerking my hand away I need to let him finish? If so that is just lovely. Why my hand branch instead of a perfectly good filthy barn boot. I knew it wasn't really a dance but it looks like it and it's what everyone around me calls it. If one of my young boys try it I just walk through them and make them back up. After a time or two they give up on me and redirect their attention to the hens. I had 1 boy who liked to flare his hackles at me, but did not flog or bite until Butter got injured. She was his favorite hen and after her stay in the house when I moved her back outside and would let her out to exercise he came running to try and breed her. She was too unsteady on her feet so I gently pushed him back on the chest. He circled around and tried it again. I again pushed him back and he crossed the line and flogged. He had a new home with full disclosure in under a week.No, it's not a sign he will turn mean. But, if you constantly reject him and fend him off in an aggressive manner he may well take a swipe at you.
In fact, when he's around stay on your feet. If you don't like this type of attention then don't pick him up anymore.
Learn what are aggressive signs, what are herding signs. You must get these things right or you will join the depressingly long list of posters who post, "I used to have such a sweet roo but now he attacks me" and as one might expect the advice is almost always to get rid of the rooster, usually by death and cooking.
Roosters do not dance, not for anyone. They herd and it's harmless. Just walk around him.
Hackle Flashing is a bit bossy. Ignore it.
In fact, read this article. It will explain a little about rooster behaviour and at least you will understand better why they do what they do. Hopefully with this knowledge you will be able to come to a working relationship.
