One my ducklings acts like he can't walk forward on his own very well. He runs away when I go to pick him up but when I leave them to their own devices he stands there. Occasionally he tries to sit down but he stands right back up and brings his whole body up. Usually when he stands back up he takes a few steps backwards and does it all again. When he does try to walk forward it's like he doesn't know how to take steps. Any reason why this might be and what I can do to help? Also, is it possible to post a short video in this thread just to show you all exactly what I mean? It's hard to describe with words.
