You should buy two, and hand raised are best. BUT will he be prepared keep handling them on a regular basis? It's really important to keep the hand raised part going, and birds can be such a great addition to the home.
We have a sensational Indian Ringneck Parrot and we just adore him.

Have you been to a shop to check some birds out? OMG I did last week and even though I don't want anymore pets I nearly came home with half the shop!
