Monday night, I went to close the chicken coops and saw a hen laying in front of it. I scooted her towards the door and she stood up, took a step or two and sat back down. I separated her and gave her food, water and oyster shell and she didn't eat or drink any of it. She did have very runny and white diarrhea and when I came near her, she did a growling noise and kind of puffed up like a broody. This morning (Wednesday) I found her dead. It's just weird because it happened so sudden and fast. If anyone has had a similar experience, please post thanks!
