They can become tame if you get them when they are very very young, and constantly handle them. You should have a pen and keep them in it for about a month before you let them free roam. Be aware that they can fly high and far if they want to, and they will not respect property boundaries.
They are noisy, very good guard "dog". But they are beautiful
