I too am going thru a crop issue with my favorite hen. She has waterbelly, which I drain as needed, but she has had a lot of fluid in her crop. She vomits brown liquid when I pick her up out of the dog crate.
Green and white runny watery poop for a week, but last night she ate some wet chick starter with some recovery 911 mixed in. This morning the poops were still runny but were chick starter color. She sits up or stands in her crate and is totally aware of her surroundings.
After reading these posts, I'm going to give her the tomatoe juice this afternoon. Not sure if I should do the Epsom salts thing.
That is my question.
