Congratulations 
@MatthewsHomestead that is a beautiful pair. My advice is that for the present you keep them captive as stock birds. Let them give you a few rounds of lovely babies, ...

 you might get 3 rounds this year.  The youngbirds will be homeset and get them flying in a group before you think about releasing the parents. Then, understand there are no guarantees, and don't fly a bird you can't afford to lose.  But basically, keeping the pair captive while they raise young is your best chance of reorienting them to your location.  It looks like a nice roomy loft and they won't suffer for not flying flee. You do your best to make them love your loft with good food, clean water, baths, treats, etc. They aren't robots,... if they get real comfy there then there's a good chance they will stay.
Again, they are gorgeous!
