I've had some aggression issues with hand-raised chicks, but not many--usually it sets in when they're older. I have a roo that was raised as an orphan, and at two months old he decided he was going to fight me. When he tried it, I would pick him up and carry him around for a while; if he thought he was going to thrash around, I'd grab his legs so that he couldn't get anywhere. If he bit me, I gave him a sharp, "Stop that!" and if he did it again, I would grab his hackles near his face and hold them for a few seconds--kind of like a "cheek grab" on a dog. It took a while, but he eventually learned that I was bigger than him and he wasn't going to win anyway, and that when he was well-behaved I was nice as pie right back.
For a chick to start in so young is worrisome, but you can certainly try the above things and see how it goes. Kind of like training dogs, be very consistent in your responses to the little rascal's actions, and try to work out positive rewards as well as corrections for bad behavior. Good luck!
