What can be done to help a lone duck/goose that is freezing into the ice on a pond, lake, etc.?
Healthy animals are capable of leaving a freezing pond when the amount of open water is not sufficient for their needs. Unfortunately, there isn’t much that can be done for animals too weak or sick to leave on their own. Since the ice is probably not safe for people to walk on, the best thing to do is to let nature take its course.
