Yesterday I went to feed my 3 day old baby ducks. They were fine till about 15 minutes after they ate. All a sudden they started falling and kicking. One by one they all died. Could it be something in the water or is there a disease that kills them after eating? Maybe too much chlorine or something in the chick starter. I have always fed them chick starter medicated and non medicated (depends which one I have currently). All my other animals seem fine. This was really strange and I am confused as to what happened. Someone said that maybe because they were thirsty they drank to much or ate too much, but would ALL of them do that.
