I can only speak for my flock. When I have young birds, I try to keep them in a pen that I can come into to feed, water etc., that way they get used to me being around. I don't try to catch them and usually by the time they're a few months old they start calming down. Until then, they drive me a little crazy! But once they calm down, I just love them!
Now, I don't know what hatchery your birds came from but from what I understand about hatcheries is that they don't have time to gentle their birds. They read that the andalusian is a flighty breed and so they think this type of behavior is normal. Well, I have never had one that wild. I think the only way your birds are going to calm down is if you get them cornered somewhere and trim those flight feathers so that they cannot go so high. You may have to do it more than once as they molt over and over their first year. Hopefully by the time they have their adult molt, they will have calmed down sufficiently that you won't have to trim them again.
... get a big fishing net from Walmart ($5-10) to catch them if you need to. You'll probably also need help. Once you catch them, they'll think you're going to eat them alive and they will struggle, they might even scream... just giving you a heads up. Good luck.
