I'm new to raising chickens, and we've been fine up until this week. On Tuesday, we didn't spend as much time outside with the chickens as usual, but when I looked out my back window in the early evening I noticed one was dead. She was roughly 15 or 16 weeks if that makes a difference. We had no clue what happened, so we hoped it was a fluke and just watched them a little more closely. This morning (Friday), my husband went out to tend to them like he does every morning and one of them had partial paralysis on half her body and was completely inconsulable, so he put her out of her misery. We think she was one of the 12 week olds. Based on my brief search, I suspect botulism. We also have ducks, so we have a pool for them that occasionally goes more than a day without being changed. We also use a waterer that holds 2 days worth of water. We're going to make all water a daily thing, but realistically can't do it more often than that. Based on what I was reading it sounded like our compost pile could be part of the problem too? So I'm wondering what I can do to help any of the others that might be sick but aren't showing symptoms get better and what realistic actions I can do to get rid of toxins and prevent this from happening again. Also, if you think it sounds like something else, please let me know. I find it strange that just the girls are dying, but that could jst be coincidence. Thank you. Oh, and I read something that mentioned apple cider vinegar, but didn't say what to do with it?
