The aerator is grounded properly.. I think the sound is what freaked them out originally Now when it if off, it just is floating and they still won't even look at it.
Hello! So I have a pretty large pond in my backyard and I have 9 ducks. They all range from a couple years to 4 months old. I just bought an aerator to place in their pond so they will have better a quality pond and I live in Michigan so I won't have to worry about them too much in the winter...
