I am so upset right now, something just are the head & brains of one of my 2 week old ducklings. it also tired to take another one, but didnt for some reason. That duckling has bite marks on the back of the neck, but thats it. The one it killed is intact,but for the head, its kind-of missing and whats left is tore up. What could it of been? The ducklings were in a plastic tote and theres blood in and on it. I'm thinking raccoon.
