I'm so sorry Michael. Yes, its good that the mom & dad are still feeding the little guy - but if he is injured, you really should take him out and take him to an avian veterinian to have him checked out. At 6 weeks of age, you can handfeed him because he doesn't need as constant feeding as younger birds do. You could feed him 3 times a day - before work, after work and before you go to bed & he will be fine with that. Of course, since he is this age and has only been parent fed, he will fight you though. Its possible that the parents will accept him back & continue to handfeed him if you only have him away for an hour or two. If the wing is allowed to heal in bad position this baby will be handicapped for life instead of healing probably and being able to fly. Good luck.
