2 Month old chick with broken leg?

[ChickensForLife]

One of our baby chicks got its leg broken (I suppose one of our large older ones hurt it by accident). We didn't know what to do and now its about 2 months old. It gets caught on things and deters her from walking up and down ramps due to her hitting it against it.
She moves alright I guess (as well as you would expect a one legged chicken to move), but I was wondering if a vet could do anything at this point? And can vets even do much for chickens?
I really hate watching her struggle and would love to do anything even if it ends with the leg needing to be amputated. Any suggestions would be helpful

Do you have photos? A vet could amputate the leg or possibly re-break it and cast it back in place. Amputation would probably be easier. I don't know let's see what some more experienced people have to say.
