I got up this AM to 2 dead and one sick duckling. At first I thought it may be the cold, but on watching the one still alive and examining the live one I saw the bills were scraped like they had been thrashing around. The live one doesn't have this however he seems to have lost some control of his legs at the thigh (hip) area. This is not predator related before we go down that road. This is either food, cold or something else. I have never seen this.. thus the inquiry.
