A couple weeks ago i found one of my ducklings on its back. i brought it inside because it kept flipping over. it died after 2 days. the first dat it was fine but it stopped eating and drinking. i never found out what was wrong with it. I have another one now, who is acting the same. it can walk backwards just fine. it doesnt have any "ouchies" that i can see. it can move its legs. holding it doesnt seem to hurt it other than it has never liked being held. one day, it was fine. than yestrday it was running and kept tripping. now it cant even sit up on its belly without flipping over, let alone walk. What's wrong with it? it is only 3 or so weeks old. (it is just now starting to loose some baby feathers). please help soon. it is still drinking, anlittle bit but i havnt seen its food supply go down.
