Need advice for a 2-yr old Buff Hen that had a pasty butt with normal colored droppings. I washed her and checked to ensure she wasn't egg bound. Next day she was normal so I put her back in coop. It's been a week but now last 2 days she's not interested in eating and has yellow/green diarreah. Her crop is fine. My coop is very clean and the run is dry. I've separated her. I was adding extra protein because a few gals decided to molt. I'm going to give her yogurt but any other ideas appreciated.
