Hi! I had three call ducks, two were about 6 weeks old and one is about 8 weeks. Over the last few days one of the 6 week old ducks started acting tired a lot more than normal and was off his food. No discharge from the nose, no funny behaviors, no crop impaction; just sleeping more than normal, green poo, and not eating much. I administered the cider vinegar, baby vitamins, and yogurt but nothing helped. Yesterday afternoon he passed on. The other two ducks that are housed with the one that died have no syptoms and are doing just fine. Any ideas? I have ruled out anything that would be contagious since the other two would have it as well. The only difference that could account for the illness I can think of is the introduction of ducklings from a hatchery, but they have been here for 2 weeks now and this duck was from a farm so exposure to 'bird bugs' happened early for him.......... oh and none of the baby ducks are ill either. I would love any information I can get since these ducks are very special and I want to try to pinpoint the cause of his death as soon as possible and to the best of my ability without doing a necropsy.
