They don't have a pond for bathing, but I gave them a nice acrylic bathtub. It's a little wider than usual and a little shallower, practically perfect for a grown goose to bathe in. I ran a pipe down the street and brought it out through a faucet, connecting a stub of a garden hose. All I have to do is tip the bathtub over, wash it and fill it. I move it from place to place from time to time so that there is no swamp there. But there are big trees growing there, they actively drink water, so there is no particular swamp there.They're so pretty and clean, @Pasha838 .
