Hello all! So grateful for you all out there all these years. Today in three months I have another chicken down. None of them are egg bound. Have read my books and looked through posts. Everything seems mostly like I am playing a bad game of darts trying to nail this thing down correctly. They start out puffed up, crouched, head tucked in, and tail slightly down with legs half bent but not sitting. They have all been weak and slowly go down over time. They will peck, groom, eat, and drink but it is minimal. The first one we brought in, placed her under heat, gave her electrolyte fluids and duramycin - 10. She lasted three more days and seizured then immediately gone. The next chicken a month later came down with similar symptoms. We brought her in as well with the same procedure. Both chickens fought hard when I would try to administer anything to them. She ended up with a very bad mite explosion. What an experience that was. We treated her for that as well. She continued to go down for two more weeks! She was finally so weak, my husband put her down gently which I hated but I could not stand to see her suffer anymore. We sterilized the coop/run, washed/bleached everything down and changed out all bedding and added in some mite control powder. Now I have another three weeks later. She is just starting to show signs today. One minute she looks fine, the next she is all bundled up again in a half squat. Their poops were never bad but just trended towards getting more bile-ish from lack of proper hydration. Any guidance is greatly appreciated. The mite experience was not fun. So I am reluctant to bring her in just yet but I know cold can really affect them at this stage more than anything. I've raised chickens for 15 years and never had anything like this. Thank you for your input and help again!
