I've been posting a lot lately about my Pekin duckling who has something wrong with her foot/leg. I originally thought it was a niacin deficiency because both of her legs were messed up. Now, I'm still wondering if that's what it could be because the other leg is fine, but her left foot is turned weird and not opening. I messed with it quite a bit a few minutes ago, and tried to put a shoe on it (no such luck), but she doesn't seem to be in pain and it doesn't appear to be a slipped tendon like I suspected earlier. Any ideas? I have a vet appointment with her tomorrow, but I'm thinking about canceling because I'm worried it won't do any good, and she's slowly doing better. Here's some pictures of her foot.
