Raccoons and fox are constantly getting my black swan eggs. I want to build a lightweight floating swan nest for my pond. Can you offer me any inexpensive, lightweight floating pond platform ideas. My husband is handicapped and can't do a lot to help me so something simple is the best idea. I also want screening small enough that the babies feet do not get caught and yet the water, rain can flow through. Thanks for all you help. I live in central Florida.
