Hello, My Vancouver urban duck experiment ended last fall, and now I need to dismantle the duck pen. I had put down a layer of pea gravel and a layer of sand, which of course has a fair amount of duck poo mixed in. Since I'm going to be moving out of this house, I need to dig it all out. Any suggestions for getting rid of the sand and gravel? I don't know if I can get a landscaping company to take it away, due to the duck poo. Thanks! Caroline PS- I miss my duckies, I miss the eggs, and I'll certainly do it again when I'm in a position to.
