This year I have 2 geese and 2 ducks. They have fee reign of my main backyard, my chickens are in a smaller section away from the veggie garden, with an auto-chicken door coop and frre range in their section. I herd the waterfowl back in their three section pen. They have two small wading pools in their pen for when we have to leave them cooped up while we're out of town. In the main yard I set up a wading pool under a young pear tree. When the pool gets murky we merely bucket out the water on the pear tree. Let me tell you, that pear tree is thriving! I have quite a few fruit trees, so next year I plan on getting more wading pools and set them up under my various trees. The ducks and geese will like it, they'll poop in them, then I'll have a wonderful manure tea for my fruit trees!
