Unless you have top level veterinary care available, I wouldn't worry about it.
I accidentally amputated a wing on a chick this past summer. I was wing banding day old chicks when I normally do them at 1 or 2 weeks. I inserted the band in the tiny wing web in the wrong spot. I got the band too close to the bone and completely severed the elbow joint. There was only skin holding it together so I had no choice but to amputate.
I have yet to be able to tell which bird it was watching them forage but there are 50 of them so time will tell.
