How to bandage a broken wing?

[thatsdebatable]

My family's keets just got out of the brooder last week and they are currently in a pen outside. A raccoon came to the pen a few days ago during the night, when the keets were roosting, and I think he reached through the chicken wire and ended up breaking the wing of one of the keets.

Anyway, the keet is dragging his wing along the ground, and since the other keets were picking on him, we separated him. He seems to be doing okay (other than the wing), since he's eating, drinking, walking around a little, and making little chirps when I come feed him. What's the best way to bandage his wing so it heals properly?

Thanks,

Update: The keet with the hurt wing is all better now! We put him back with the rest of the keets a few weeks ago and had no problems with other keets hassling him.
