I do show, however, skittish chickens drive me nuts.
That's why I want them to be used to people. It really gets on my nerves when a chicken darts off like I'm about to kill it when I even go within 10 feet of them. It also makes it hard to catch them when the need arises. I always have to spray my chickens for lice and mites in the summer thanks to the wildlife.
It's just my preference: I want tame, docile chickens.
Therein lies the problem with your little rooster. He's so used to people that he doesn't have the necessary wariness of them, as any smart chicken should. People are predators, no matter how nice you are to your chickens or how much you pet them, we are larger, we are and should be considered dangerous to them. When chickens are bred for the characteristic of docility, sometimes it doesn't always work that way. A rooster is not usually a docile animal....many people report having friendly, docile roos and I know they are out there, but the norm for a male chicken is dominant, wary, and defensive when it comes to his flock and anything larger than he is coming in contact with them.
What you have is a young rooster that has absolutely no healthy fear of humans and he should. All roosters should to some degree...this is what keeps them from flogging our heads off when we bend over to fill feeders and waterers, pick up a hen, do anything at all in the vicinity of these birds. These birds have the natural inclination to breed and defend....breeding that out of them doesn't always work and I wouldn't give two shakes for the virility of a rooster that is so docile that he doesn't have some defensive or wary attitude in regards to his flock.
It's really up to you on this one....do you want a rooster that is going to be that dangerous to you or do you want to have a rooster that isn't skittish in your presence? Having both a docile but safe roo is pretty rare...they are out there but 9 out of 10 roos will not be big, lovable, cuddle bugs that will never flog you when your defenses are down and can be picked up anytime you wish.
The best you can hope for, consistently, is a rooster that doesn't flog you or any other human because they have either natural born wariness or respect for the predator in a human or that you have trained to have a respect for you and other humans.
In my barnyard chickens, especially roos, are taught the echelon or hierarchy of animals~human, dogs, chickens. Humans feed and care for them and the dogs guard them from predators and the rooster needs to learn his place in that order or suffer the consequences. He has two large preds walking around in his space and they could end his life in a matter of seconds if he forgets that place...a smart roo doesn't take long to learn this fact.
You often can't have your cake and eat it all up too....this is where you will have to decide if you want a pet that attacks you or a rooster that is wary of you and walks a wide berth around you when you care for your flock. If you want the latter, you need to school this young roo real quick. If you don't wish to do so, you can get rid of him but I imagine you will have the same problem pop up again in your attempts to hand feed and coddle a male chicken. With roosters, that level of familiarity often breeds contempt.
ETA: You might want to switch your efforts for hands on care of the chickens to night time where you can simply and quietly lift them off the roost, treat them and replace them to their original place. That eliminates all the need for handling, petting, taming to try and make chickens docile enough for infrequent handling needs.
