I do not have ducks, or geese,,,, but do understand that they drink differently. Is the bowl deep enough to submerge the duck's beak/head sufficiently??? I would set it up, and observe if the ducks/geese use it, and results. I would of course have a separate bowl with water around, but in a different location. If ducks really would need to,,, they would find second bowl.
My second question,,, and only can be answered after sometime of use is,,,, How easy is it to clean when needed. It looks like it needs to be mounted to wall or similar.
