Birds bones are hollow and when they break they don't heal right, usually. It's very very hard to set a wing correctly without x-rays.
That said, it can still be a great pigeon.
If you do decide to keep him, I would make steps around the aviary for him to up and around.
Birds do heal remarkably well, but with wing injuries, they often heal wrong or skewed. He may be able to get some sort of flight, but won't fly normal again. If it's important you home (fly) him, I would cull. But he could make a great 'pumper' (pigeon that raises other pigeons squabs). Since you won't know his 'skills' (how well of a homer he is) I wouldn't suggest breeding him (or you can for fun and see how the squabs are) but you can take advantage of the fact that he'll want to raise up squabs, and steal eggs from other birds and put them under him. They'll lay more eggs, so out of 2 pigeons you can get 4 squabs instead of 2.
Best of luck. I have a pigeon missing a toe, and his son has a genetically deformed toe. He was feral caught so I don't know if he lost the toe or what, but his son was born with this screwed toe. He also lost a good chunk of his wing and healed just fine. They're great birds, that are very hardy. But in this case yours wouldn't be able to be raced.
