We've just purchased a home that came with a 100'pond and 3 spoiled ducks. Can anyone suggest a way that I can keep the ducks on only one half of the pond. They have free range of 3 acres and I'd like to limit their access. A fence is easy enough on land but I'm stumped on how to divide the pond. It's about 6-8'deep, and 100' long with a 45' bridge that spans the width.
