We have a "pair" of ducks, on Mallard female, one Runner male - they are about a year old. The female just hatched 15 ducklings in the last couple of days. We have a large irrigation pond, where they swim every day. They took the babies to the pond today for their first swim, and we noticed that the drake is sort of aggressive towards them, chasing and snapping a little. Should we separate him? It seems harsh, since he was so dedicated to her while she was sitting on the eggs, but I'm a little concerned he will actually hurt the babies. Also, am I wrong or is 15 a lot of ducklings for one mamma duck?
