Our school has an area south of campus affectionately known as "The Duck Pond". These ducks were originally wild, but over the years have become more domesticated and a lot more numerous. As such they do not migrate for the winter and choose to hang around the grassy area the pond is kept. The problem with this is that there really isn't any food there for them. There are at least 50 ducks there and I watch them forage for what looks like nothing. I'm just concerned about them as it's really cold now and there are so many mouths to feed. Do I need to take action or will the population take care of itself? I couldn't tell if any were skinny or not.
