They actually tame up well on their own when they’re grown. They learn fast who feeds them and warm up accordingly. They are easy to hand feed and they often light on my shoulder like parrots wanting a treat. They’re most flighty and skittish when they’re chicks and sub adults, and a lot of their “wild” has more to do with how they free range. They come into confidence as they mature.
I don’t handle mine much though because I have concerns that excessive handling leads to human aggression. That’s just a hypothesis, I don’t have enough data to confirm or deny it. When I obtained this flock going on 2 years ago, 3 of my 4 roosters that I allowed to mature were terrible manfighters. The 4th was calm and confident and human friendly. That was/is “Hei Hei” and he became the father of my flock. Your eggs are off of Hei Hei’s children and grandchildren, which are the best of my best roosters that have survived multiple selection culls by myself. None show any human aggression. Yet, I also produced offspring off the manfighters and none of them are manfighters either. There was something unique to those original 3 birds that made them human aggressive that didn’t translate to their descendants. I raised 1 myself and family raised the other 2. All 3 were heavily coddled as young cockerels, while Hei Hei was raised at arm’s length. Therefore I speculate that perhaps their raising made them not keep a healthy fear of humans and to the extent they have true wildness in them, losing a fear of man makes them dangerous like a tame whitetail buck during the rut. But that’s just my guess. Its just as possible the farmer I got them off of incubated them poorly and their manfighting traits might have been an incubation defect.
