Hello I have a duck that is 9 years old and he's never had any issues for all 9 years but last few days he started to struggle to walk and is feeling little weak mostly sleeps he drinks water and eats but as eating he doesn't eat much we feed him with grain wheat, leafy greens , cucumbers and his favorite is tomatoes also loves cat food. we had him to the vet but vet never had any experience with birds they gave him vitamins and he seems little stronger today but was wondering if anyone had similar experience with ducks that could suggest anything to help I really appreciate, we are going to take him to zoo tomorrow because the vet we usually go for our cat & dog is really good but she never had any experience with birds so at zoo they most likely have vets that know about birds so will see what they will tell us 
meanwhile ill read other similar posts thank you all in advance.
