This morning she seems perky, only 1 poo last night and not very big. Then again all she ate yesterday was 2 eggs and yogurt. I mixed up a mash of food, yogurt, and canned pumpkin - hopefully to clean her out. She has access to food and clean water, but doesn't seem to be drinking much. The food is very moist, so hopefully that will help. I will monitor her intake and output today in the crate.
Her crop was empty this morning, but sort of like an "after" biggest looser - not flat, but empty. I think she was really stretched out. When there is some more poo to compare, I will let you know. unfortunately right now it looks like the egg peritonitis poo! small bits of solid with lots of white. I know the white is pee, so fluid is getting through. I didn't feel anything that feels like a solid egg down there. I need to check the other hens to see what their bum feels like to compare. I will let you all know.
Thank you all for your responses. I can post pics of her if you think it would help, but since it seems to be an "inside" job - not sure if it would - let me know.
She doesn't seem as wobbly today, but she is locked in a dog crate.
