On Sunday some animal took one of my two pet ducks (they were imprinted on one another) so I got two females for Pablo thinking that would make him feel better. Today I was gone for two hours and an animal killed the two girls and spaired Pablo. However they left one dead dunk in the pen. Now he won't hold his head up he will walk but he just hangs his head. I am really scared I am going to loose him he isn't acting even remotely like himself. He had no injurys that I could identify only a tiny tiny scratch on his leg. I don't know if this is duck ptsd from watching three of his kind die in front of him or what. Could he be bleeding internally? Is it shock? Is it depression? I have no idea but I'm scared please help Pablo please please please. Just tell me what I should do? Should I buy a heater near him? Give him sugar water? I just don't know and the I ternet sucks.
