According to her it was running and fell, that's when she picked it up and was carrying to me. They being feed an all flock raiser. Also this just happened today. It hasn't had problem before. It unable (or chooses not to pretty sure it can't) stand or put its leg down. When I had them in the tub this duckling kept its legs straight back and would kick but only like a person swimming not a duck. As where the other would stand in the water this one would not and after awhile it could no longer hold its head up out of the water. It's been in a box for awhile and hasnt stood up or walked.
