When I let them out this morning, my oldest duck held back and came out slower, and when she got out to the yard, she walked around slowly, half heartedly nibbling at grass and totally not acting like herself at all. Usually she's the crazy one, talking the most, and running off as leader of the group. I caught her (too easily) and set her up in quarantine with food and water. I cooked her some eggs, chopped tomato, cucumber (peeled), two garlic cloves, and some clover. She nibbled, didn't eat it. So, she's off her food. She drinks water. She seems to have diarrhea, first I saw from her was green and mostly water (dark green like vegetation), and after putting her up, white and VERY watery, nothing to it at all, just liquid. Or could this also be from not eating? Breathing is fine. Eyes are clear. No discharge. Crop feels soft and squishy like normal. Rear end feels normal and isn't distended as far as I can tell. She started laying a week ago, laid every morning for 3 mornings, laid one soft shelled egg, took the next morning off, then laid every morning there after, this morning included, normal eggs. Yesterday she did a weird thing. She was acting fine, but started shaking her head from side to side, seemed to vomit, and then went on about her day as normal. I thought she had eaten something she didn't like and half swallowed it, got rid of it, and was fine. When I went and looked at it, it was grass and a couple of leaves covered in slime.. duck spit and stomach fluids I guess... totally clear, no color. She was eating normal yesterday. Not today. She half heartedly preens herself, but did not go swimming. Didn't do her usual "OMG clean water" insanity. Any ideas? Need any more info? She's on a basic layer feed with daily fresh greens and veggies. Still has some grower mixed in for the younger ducks. She's just shy of 7 months old. Looked at her feet, she appeared to have one cut and minor swelling with it, normal coloring, no ooze, is that mild bumblefoot? Would that cause her to go off her food and get lethargic, that tiny little thing? Doesn't look like much of anything, but should I treat it and wrap it while I have her put up? I was thinking I would when husband gets home and can hold her while I doctor it. She was favoring that foot when she was walking, like a slow motion waddle a little more pronounced than normal... not bad looking, but different enough to make me look at her foot.
