A couple of muscovy ducks have found my floating dock and the fish feeder that hangs over the edge. They $h!T massive amounts on the dock, causing green mold or mildew-like build-up on the deck boards. I want to scrub down the dock and gangway and re-stain it. I don't want the duck to ruin it again. I'd like to take a .22 to their cranium, but the land owner says he "kinda" likes having them around. Yea, they are nice to look at, but contaminate my dock.

Anyone know of a solution to keep the ducks off a dock? Thanks.
