I have 4 young ducks and 2 geese. I also have a 2 acre pond I hoped they would use and look beautiful on. But they won't! My wife and I have "herded" them down to and onto the lake on at least 4 different occasions, they start dabbling and splashing having a grand old time, but the moment we leave they get out and don't return unless we herd them!? When they were much smaller they would get in there drinking tub and sit in it all lined up in a row. Then they made themselves home in my horse's 50 gal water trough which I have to empty ,clean and refill at least once a day and it's killing my back. Any suggestions on making them all happy to spend their time on the pond??
