I just took in a duck that was dumped at a lake with a clipped wing. I think because he couldn't get away properly he might have tangled his foot somehow. I don't see anything broken and it all moves ok but he won't put weight on his foot and hobbles around pretty bad. Is there anything I can do to help him? Will rest be enough? I am not sure splinting it would work since it is his ankle. We have him separated and relaxing to see if that will help at least. He was being chased by the geese so he couldn't get rest.
