My hamster may have a broken toe?

  Well her toe looks a little weird. And maybe like it has a scab on it. But she seems completely unaffected by it. She still runs around and eats and everything. So should I just let it be and just keep an eye on it?
You can't really do a whole lot for a small animal like a hamster. You have to just let it be and have it heal on its own. As long as it can still eat and drink it'll be fine.
get it to the vet, it can become infected
