I have 3 geese that are about 2 weeks old and 8 ducks the same age. The ducks can't help but go swimming as soon as they see water. The geese come to the edge and dip their head in and bathe outside of the pool. I thought that they would really love to get in and splash but they don't seem to at all. It is just an observation not a concern. Once the ducks start splashing the geese get the zoomies though.
