Or eats them at all? I found one of my Rouen duck's ducklings floating in a water pan they use for bathing. The pan is short enough that they (ducklings) can get out so it's not the problem. The duckling's beak and both feet were missing and that's it. It was crested, and the crest area was 'messed up' but wasn't really eaten. What animal will eat these parts?
