I would talk to the breeder of the ringneck about taming. Was the baby ringneck handfed? Maybe he doesn't let you pet him because he's not used to humans handling him. Plus, he's just a baby. I think with a little bit of work, he'll open up for you and let you pet him and stuff. But like I said before, maybe talk to the breeder? Can you meet the parents of the bird and see how the parents act around the breeder? (like if they let the breeder handle them and stuff)
