I live in Texas and I also had two ducks die within 18 hours of one another. Both females, 6 months old. They displayed no visible symptoms other than suddenly they weren't interested in eating or drinking, didn't want to socialize with the other ducks or birds. The first one died yesterday after lying alone for several hours by herself, head forward, feet back, body mostly soft and pliable. There was no sign of discharge on the face and vent was clear. When I noticed her lagging behind and uninterested in eating, I checked her to make sure she wasn't egg-bound. Her abdomen was soft and her crop was soft. Her sister began displaying the same lethargic behavior about 6 hours after she did. The first duck died yesterday about 5pm, her sister died overnight last night. Does anyone have any idea what happened to my babies? I don't have the funds for a autopsy at this time, but if we lose anymore ducks, I may have to take one of them to A&M.
