For several weeks now one of our chickens has had diarrhea. When it first started we wormed the flock, knowing we were due anyway and a few had abnormal poops. After the worming they all had better poop except once. I think I have it narrowed down to 2 of the 9 (after going out early one morning and seeing where they are sleeping since they are not always consistent). One of them is not hanging out with the rest of the flock as much as the others either, though she never really has. We had a cold spell last week and she was going into the coop around 2 or 3 when the rest didn't go in until at least 4. I see her eat and drink still, but the eating does seem to be less. And the last few days the diarrhea has gotten worse. I took a picture of it today and will see if I can post it. I have looked up possibly causes and none of them catch my attention. There has never been blood, just the urates and intestinal shedding. I have considered taking a sample to the vet (I doubt my husband would go for that though). Does anyone have an idea what that would cost? The bird I am suspecting showed up at our neighbors house 6 months ago and gave us several eggs a week all summer so I doubt she is that old, though we do not know for sure. Sorry, this got long. But any help would be appreciated!
