She's a four year old black australorp. She started acting different 2 days ago, hanging out by herself. Yesterday she acted like she was going to lay an egg in the outdoor pen, ruffling up her feathers and walking with her butt almost dragging along the ground. But she was lively and didn't seem to be in any pain, so I waited. Today she has white runny poop alternating with firm whitish poop, and is still looking under herself to see if she layed an egg and it looks like she is straining a bit. The feathers on her back keep moving(in waves) . She is still picking at food. Any idea what is going on? I probably should cull her, but I hate to. She's a really nice hen. Merry
