We have 5 chickens who are 24 weeks old. They were vaccinated as day old chicks before they were shipped. We live in Denver. One of the 5 started laying Jan 2 and has laid 6 eggs since then! Yesterday and today she seems to have diarrhea. I've been reading and looking at pictures and I can't tell between the looks of Clostridium perfrigens or general diarrhea. Our chickens live in very clean area, mostly because it's new. Would she be old enough to get Clostridium perfringens? I've read all kinds of things can cause diarrhea (stress, heat, sudden cold etc...) but she seems to be the only one who has it. She's eating and acting normal. She's the "alpha" hen, a Golden Buff (Comet). I haven't read anything stating that starting to lay eggs can cause stress (and diarrhea) but I've wondered if that could be it? It would make the most sense since she's the only chicken of 8 (the other 3 are 21 wks) that is having this problem. We did have sudden cold and more snow a couple of days ago, but again, none of the other chickens are having diarrhea. Any thoughts?
