Tuesday, August 20, where my 6 year old hen slept was a bright red bloody poo. I suspected coccidiosis. I bleached the poop board and and waterers and quarantined her until I could get off work. At home, there was no poop, bloody or otherwise, in the cage where she had been quarantined. She had eaten all the food I gave her and was upright and very strong. I began treating the entire flock with Sulmet. That night, the hen got into and slept in the nesting box instead of the roost. Wed, she got up and out with the flock, but didn't eat well. Just pecked around. Just stood around. The same Thursday. Slept again in the nesting box. Friday she was up and eating. I felt very encouraged. She still slept in the nesting box. Then yesterday, Saturday, she seemed to eat pretty well. No bloody poops. Last night, she got herself up to the roost with the other chickens. Seemed like we had turrned a corner. This morning, she woke up with a belly full of what feels like fluid. Doesn't look well. Any advice appreciated.
