I claimed 4 ducks from my husband's grandmother who has decided to give her duck flock away. However, when I claimed them, my duck house wasn't quite ready, so she agreed to keep them 'till I could finish it. A month or so later, my ducks and my grandmother's geese have been sharing a handful of nests, and I now have two young ones. One of them is definitely a swedish duck. The other I am fairly positive is a gosling. However, the gosling is somewhat shaky on its feet. Is there something I can do to help it? It hasn't been flipping over to it's back or anything, but it is wobbly. It falls down (onto its belly) when it shakes, etc. Any ideas?
