Hello everyone, I have a duck that cant stand upright, he waddles around. I have done just about everything. I have given it niacin and brewers yeast. I have also mixed his food with better duck food. Me and my mom give them healthy human food for them. Fruits, tuna, chicken and greens. But nothing seems to work. I am now starting to give it magnesium for its bones and muscle health. It hurts my heart because we might have to put him down. Im not quite sure what are other duck will do or act without him. Any suggestions will help guys. Heres some photos.
