Sorry, but with this video all I see is a rooster trying to defend himself against an aggressive boot. Are you saying that he also goes after you when you go out to do chores? There's a difference between an aggressive roo and a defensive one - although admittedly it's a fine line. What we may see as aggression is, to him, defending himself, his flock, and his territory.
If, indeed, he aggressively goes after you or others for no apparent reason, then there are ways to try to curb that, but it takes a lot of time, dedication, and a hard heart on your part. If that's what you want to do, then you can type "aggressive rooster" in your search box (without the quotation marks) and see what others have done. But if he was mine, he'd be no part of any breeding program and he'd be holding down a spot in the freezer.
