Based on my reading on this site, I figured my pond shouldn't have more than 2-3 ducks. My mother in law became over-enthusiastic at Tractor Supply and bought five. Those five ate tens of thousands of frog eggs, tadpoles, and salamander eggs in a single weekend and acted ravenously hungry all the time. In addition to the natural wildlife appearing, it was clear that I was going to have an overpopulation issue. Thus, not all 5 made it to old age.
