I have tried everything that I can think of. Niacin, infant vitamins, vitamin E, and brewers yeast. I realized that the hip was dislocated so I tried to wrap it up in the correct position. That was like brushing your teeth while eating oreo cookies! The little booger was to squirmy and after trying mulitple things to wrap it with I finally had some luck with "free wrap" from my daughters softball bag. That lasted all of 2 minutes before he wiggled it right down to his bum and off. I have been holding him for long periods of time with the leg in the correct position and he is starting to put weight on it now occasionally but his foot still turns wrong and is all smashed up so I don't think he would be able to swim and certainly not mate, which was my long term goal. Without any other suggestions, I guess I will focus on making sure he isn't in pain and plan for having a special needs duck. All of mine free range from morning to dark and "Deeks" wouldn't be able to so I will start to work on a new pen for him.
