Hi I have 2 female pekin ducklings that are 2 weeks old. One of them has wings that are perfectly formed, the other does not. She has one wing that is normal, and the other one is almost completely bare and is bent at an odd angle. It doesn't fold in like the other, it just lies uncurled on the side of the body. I'm not sure if its angle wing because it doesn't stick out of the body. Is there something wrong with her? Thanks!
