Puddle ducks probably do not eat very many if any minnows, and I'm pretty sure they eat mostly bugs, organic muck items, weed seeds, aquatic vegetation and plant tubors. My dad and I raised ducks and geese on our pond in its early years. However I am suspect of most diving ducks. I have watched through binoculars Mergansers eat small 4"-5" yellow perch in my Ohio pond.
