I have a now 22-day old Pekin duckling that has leg problems. His legs cross over one another between the knee and foot. He can't walk and just kind of pushes himself along the floor or ground. I was trying to work with him by letting him swim in the bathtub but today he can't even swim. His legs hit one another causing him to go under and the only way he can keep his head above water is if I hold his chest up. I had hoped it was just a small problem but I'm thinking now he'll have this for the rest of his life. I have no info on disabled ducks or keeping a duck in the house. So any advice would be wonderful and maybe even some ideas on something I can make him at home that will help him walk. He started out 100% normal but after a fall he's become like this. He's eating and drinking, peeping and seems happy otherwise.
