Injured baby duck

[Sooma]

I have a baby ducks that's a couple of weeks old. Somehow my cat got to it and stripped off its feathers on one leg and the ducks isn't moving that leg. I tried to seek professional help but I needed an appointment. I scheduled an appointment, and the soonest one is in three days and Im worried the duck won't survive till then. I need an advice on how to treat the duck in the meantime to keep it stable until the appointment. There is no bleeding but the site of injury is beefy red. I appreciate any advice, I'm new to this and this is my first duck.

So sorry about your duckling. Anyway you can post pictures of the affected leg? There are no bite wounds. Scratches?
