I'm a first time duck owner I started out with 11 baby ducks and 5 African geese. There 3 weeks old. I've been putting them in outside pen during the day and today the dog got in there and killed 3 ducks and 1 goose. I have 2 geese that are injured. They both have hurt legs and won't stand up. the one in worst shape is bleeding and his foot is cold and limp. The other one is not bleeding he trys to stand but is unable to put pressure on one leg. When I hold him he moves his foot. What should I do?
