I'm still really new to raising ducks, but one my older ducks - an adult drake seems to have attacked one of my younger 2 month old ducklings. The adult drake is currently on his own and does not have access to the other ducks. The duckling the drake attacked keeps shaking her head. Her behavior is mostly normal otherwise (preening, swimming, etc), but when I picked her up and looked at her eyes, one seemed to be sort of pushed downwards into the socket. Is there anything I can do to get her eye back to normal or help her out?
