Every time I fed him and the others, I kept stroking their back. Talking to them softly. Picking them up every now and then for 5 seconds then setting him back down, he didn't even complain half of the time.
That doest work for birds due to their hierarchy.Next time I may try that just for males but the whole premise of my hand rearing and physical content is constant acclimation with positive reinforcement.
You want to be hands off, no petting or hand feeding. No touchy besides getting him used to health checks.
Pretty much ignore him unless you need to make him submit
