If you can keep your Runner inside from now on, s/he may have a chance. Put hydrogen peroxide on the wounded area once or twice for the first day or two just to sterilize it, then only use water to clean because HP can also damage live tissue. Then I would put a very thorough ammount of wonder dust over that. This is the method we used for Scuttle, my duck that had a chank bitten out of her thigh. She wouldn't eat or drink the first day, and not much the second day. She also had fly maggots growing in her wound when I found her. A fews days laters she talked to me every time I walked on the porch. A week later she's back outside and barely limping. (She's probably rather be with people though, becuase she's gotten used to us and the other ducks are really giving her a hard time so far.) The wound has already healed up quite a bit. If you can't keep your duck inside unfortunately I think the kindest choice would be some form of humane euthanasia.
Good luck.
