Whatever this was has squeezed through small holes dug underneath the pen. I had a Muscovy in with a full grown turkey so I thought she was safe. This predator dug into one of my chicken coops. Never touched and chickens. Turkey had neck feathers missing but otherwise safe. Predator tried to pull duck through small hole it used for entry. None of the 12 ducks killed were eaten. Only marks were punctures on necks.
