Just incase anyone didn't know what happens to those beautiful waterlilies (any other water plant for that matter ) that you have in your pond once you get ducks, here you go. My waterlilies were 3 years old now, very well established,covered that entire area, and had 6-8 inch pads and 4-5 inch lilies on them until we decided to let the ducks just have the pond. I just got some water lettuce to see if they wil eat that, so far they haven't but it has only been two days. At least we have a top pond that they don't seem to realize is there and that is were all of our pretty flowers grown now. I guess it is worth it to see my ducks so happy.
