My husband bought me two ducks a month ago from Rural King and everything was perfectly fine with them both, but as they grew up one started having trouble walking. One was smaller and is fine, but the other grew big very fast and started walking a bit pigeon toed and had trouble balancing. Now he has gone downhill to where he wont walk anymore. Even when my dog approaches and sniffs he just lays there when the other one runs off. I have given them the only duck feed that Rural King carried so I don't know if the food is the issue. My husband called the vets around but they specialize in dogs and cats so they cant help. I don't know what to do. I moved the water and food so its within reach.
