Medical Care for feral kitten with broken leg

We found a feral kitten with a broken leg. The goal is to get her fully healthy, likely via amputation, and find her a good home. If you have any questions, please ask! I'm sorry for the lack of video. I can't figure out how to upload it. Not that I imagine anyone particularly wants to see a kitten with a broken leg, but thats the best way I can think of to assure people this isn't some scam.
