I came home last week to a frantic flock with most of my ducks gone and one runner laying on her breast. My runners are not overly people friendly so as I approached and she didn't head for the hills I knew something was really off. I picked her up and she was hissing away. When I put her back down her feet were stretched behind her . I put her in a crate and ran off to see where the rest could be. They were gone. I came back to inspect her and all I can find is one small puncture wound in her wing. I cleaned it up quieted her down, put food, light, and water, and hoped for the best. The next day she was up but she can't stay that way she falls face first with her legs extended behind her. I put her in water and she swims beautifully and the ones that are left came to inspect. However, as soon as she hits land its back on her face. There is no marked improvement in the past few days any ideas? Do I continue to wait? I don't want her to suffer. She is eating and drinking. Our ducks and chickens are pets and eggs only btw so to cull for us is a huge deal
