I have an ill duck I need a hand with. She started acting off two days ago, in the morning she was fine, when my husband went to feed the ducks in the evening, he said she was just lying on the ramp to the coop making funny sounds (almost the sounds of a person shivering) and would not move when everyone else went in the coop. (They walked on her and she just sat there.) When my husband went to pick her up, she started running from him, but he said she seemed a bit wobbly. He brought her in and put her in the tub with water, cleaned her up and checked her over for injuries. He could find nothing wrong and she was cleaning herself in the water. So he put her back out with the flock.
Later on I came home, and she was again just laying in the coop run, she did get up and follow the flock when I went in. I again looked her over and she seems okay. Her eyes are clear and alert, nothing coming out of her nose, beak wasn't dull, legs and feet had no cuts, breathing fine, feathers still looked good.
The next morning, I went out to feed the ducks before work and this time you could see she is physically weak and using her wings to keep her balance when trying to walk. I noticed she keeps wagging her tail A LOT. So I brought her in the house, put her in a kennel with fresh food and water.
When I got home from work I checked on her and she had not touched her food or water all day. She is still alert but using her wings even more to get around, her poo was green and white solid with some water to it. Her breathing when she is excited sounds labored, but when calm she is breathing fine again.
Her eyes dialate normal, still clear and alert, and still nothing coming from her nose. Checked her vent and it looked good too.
Using the Homestead Duck and Goose feed, same stuff for months, and none of the others are having issues.
Thoughts please?
