I know one of my 1 year old RSL hens is sick. In the morning she is puffed up and standing still in the corner, but warms up quickly as daylight increases and has a pretty normal day. She has white diarrhea almost all day but has some regular feces. In the morning she has a massive amount of bright orange diarrhea. She is eating and drinking normally and walks around clucking. When I pick her up, she vomits water and excretes diarrhea. I hear her gurgling from her throat and I hear air escaping from both ends and if I examine her by feeling her abdomen, crop or breast, she is in obvious pain. I know she's ill, but I can't identify the problem. I have 20 other hens who are acting normal. I have lost 3 other hens in the past 6 months to egg bound, egg peritonitis and unknown illnesses. Any ideas?
