We have 2 pekin ducks that are about 2 months old. When they were smaller we used to take them out to the koi ponds in the front yard and they loved it. Now that they have kind of outgrown the little ponds we have been taking them to our large (3/4 ac) pond instead. They don't like it thought and will never stay in the water. Is it just because the pond is too big? or because they are too young? If we take them to the koi pond they still love it and swim around but they are just too big for it. Any thoughts? Is there something we can do to encourage them to use the big pond?
