We have a small flock of ducks, less than a year old, and this morning we found one of them sitting in the yard, not walking around with the others. She was very sluggish, wasn't eating, wasn't eliminating, and if you put your ear really close to her nostrils she was snuffling a little bit. We figured maybe she was egg bound, so we soaked her in epsom salt and did our best to keep her warm and separated in a small cat carrier. A few hours later, they found her dead. I tried researching, and can't figure out what was wrong with her. There were so few symptoms that it's really hard to know. This has happened with our chickens so many times, and now a duck..... ugh. I'd really like to stop losing my flock without being able to help them.
