Frank were they able to fly at all? I know the Mallards could as my boys that I have sold people have flown away never to be seen again. Runner ducks are not supposed to be able to fly yet the guy I bought my two babies from last year said his flock flew very well. My huge Mule duck can fly as high as my house with one wing clipped! I could not believe she would be able to do that.Indeed. I have never found anything left from a duck that became victim of a predator. Not a single feather, it is as if Beamy scotted them up.
