He has been through a lot of disruptions in his daily life lately not to mention the hormones have kicked in. I'm not surprised he's acting a little crazy. Give him some time and space and let him settle down. I would not mess with him other then normal day to day care of the flock. Just let him be for a while. Although if he advances and wants to challenge or flog you then you need to put a stop to it, then carry on with what you were doing. I realize you were lucky enough to have a very docile rooster in the past but the truth is that many, many roosters just are not like that once they mature. Most of us are happy with our roo's if we can raise them up to be respectful of us and keep their distance. That's about all I expect from mine other then treating their hens well of course. I don't expect them to be pets in the way my dogs and cats are, it's just not their nature.
As far as treats...I don't hand feed to him, I toss out treats for the hens and he stands back and watches them or he "helps" by picking some up and feeding it to the nearest hens. When they have all had some he will clean up any leftovers.
In regards to handling roo's a lot. I've always had much better success with roo's that I did NOT handle and coddle a lot as youngsters. My first ones, I handled all the time and they were the worst as far as aggession when they hit maturity. They had no natural fear or respect at all. The ones that I handled only as needed for normal care were much, much better.
