See if you can set the bone first by holding the body and pulling the wing at the second joint, you should be able to feel the bone come together. Then you'll want to use electrical tape or masking tape and while holding the wing folded together against the body, wrap the tape around the body and wing fastening it in place against the body to keep it immobilized. You'll need to leave it like this for at least six weeks probably eight since hollow bones heal slower. Hope this helps.
Birds are resilient creatures and while it may not be able to fly it will be able to live a productive life. I've had birds with broken bones, shattered, that have fully recovered and lived for several years after.
Blessings,
