I’ve lost my 2 jumbo Pekin ducks just days apart. I found My first duck about 4 days ago and she was out of her pen when I found her, she was about 20 feet from it. She was missing her feather, skin and meat off her back. She was also missing tail and neck feathers. She had a big puncher wound on her head and smaller one on her neck. She was still alive when I found her but passed shortly after. We than put a covering over the top of the pen. Today I went out to find her mate dead in the pen. He looked like his neck was broken and was missing feathers and skin and only a little bit of meat off his breast. I really thought a bald eagle had gotten to the first one but now with the second one I’m completely stumped and confused on what could have done this. Also all of my chickens are fine, and that also confuses me as to why it went after the ducks and not the chickens. Any ideas?
