Does anyone here know how to build a floating duck platform? I would love to build one for the middle of my pond for my ducks with an attached house. I assume I can build it out of treated deck boards but need to know what would be the best thing to use underneath to keep it afloat. I was planning on using an anchor to keep it in the middle of the pond. I can use the canoe to get over there for any maintenance that may need to be done. Any help would be greatly appreciated!
