I have a pair of 1 year old Pekin ducks. The female is barely able to walk more than three or four feet without lying down and spreading her wings open. I don't know if its her wing but it seems to be more than one thing bothering her. The male gets a little rough with her so I didn't know if maybe that was what cause injury but I am more concerned with getting her treated. I cannot identify the problem - she almost acts like she has an egg stuck that she can't lay or something ...she acts like she's having some kind of contraction in her midsection then just spreads her wings and sits. She spent all day in the water yesterday which I thought was funny because she's usually is out more than she is in. then I figured out that she could barely get out of the pond and so I picked ber up and took her into their den in the barn. I wanted to make sure she was going to be able to eat and drink overnight and be sure she be okay today. She appears wose today. I called my vet, three or four other vets and also several extensions of Wildlife and Ohio State University farm animal division. Nobody can help me. If she were wild it would be no problem but since she is domesticated nobody will take her on. I don't want to see her suffer and I need to know what's going on and if she is treatable. She is a pet and I love her like any of my other pets and I don't want her to be in pain. Any suggestions?
