A good portion of the outcome is dependant on individual personality. Some birds are just not into human interaction and you can't convince them otherwise. I've been involved in parrot and raptor rehab, in addition to keeping chickens; that seems to hold true for any bird. You might have one bird that has little to no previous interaction with people be easily "tamed" to accept human contact/presence while another could be carefully hand-raised yet never fully accept human contact. Not all methods will work well for every personality of bird, and you have to gauge the bird's response and adapt your own actions accordingly. If you take an anxious, flighty bird and repeatedly force it to accept human contact without it being on the bird's terms, it would probably backfire on you and make the bird even more averse to humans. Birds are smart and stubborn.
