This morning everyone was fine. I went to run errands in the early afternoon and only counted six ducks, but saw one was in the pool by herself, but she appeared okay. When I returned 1 1/2 hours later she was hanging out with the other ducks and everyone seemed normal. Then, about an our ago, I went out and she was again alone in the pool and wouldn't come out and appeared quite lethargic. I lifted her out and set her down and she could barely stand up. She felt a little cold, so I brought her in and tried to warm her gently with a hair dryer. I've got her in a nest of straw and she seems to be having muscle spasms (her wings keep fluttering) but other than that she is moving around very little. I've looked around to see if there is something toxic she could have gotten into, but I really don't see anything at all. We do have mushrooms that grow wild here, but I've always assumed that the ducks and chickens would know whether they should eat them or not - though I looked around and didn't see any mushrooms growing in the area either. I'm quite worried, because she seems to be fluttering her eyes closed as if I could lose her at any minute and have NO idea what to do or not do. All the other ducks seem fine for the moment. Any thoughts on what I should or shouldn't try to do? Update - Lil' Blue survived the night and is looking back to normal, but will leave the post in case anyone else experiences something similar.
