I have a sick hen that's about 6 months old - 4 days ago she was unable to walk and stopped eating and drinking. I separated her from the flock and have been feeding her by hand twice a day and giving her water from a syringe with Sulmet antibiotics. (It seemed like Coccidiosis and the local feed store recommended Sulmet) No imporvment after 4 days, and tonight another hen has the symptoms Do I need to cull them both? Any advice please help! Symptoms: lay in nesting box instead of on perch at night won't eat or drink on their own very lethargic unable to stand on their own heads bobs and moves - can't really hold still or hold head up poop - clear and watery, no blood that I have seen I'm pretty sure if I stop feeding them by hand they will die - maybe I need to do that now?
