Indie, approx 11 month-old Easter Egger, started self-separating about 3 weeks ago. She started being bullied by the old girls, appetite decreased and she became very timid. I treated them all with Corid in case of Cocci. She has lost a good deal of weight (and she was small to start... both my EEs are smaller). I brought her inside about 5 days ago. She has slowly stopped eating, then drinking. She still interacts well with us, but she’s super slow. I began tube feeding and watering on Thursday (3 days ago). She also has a great deal of green diarrhea. Sometimes she passes 100% liquid, sometimes there’s some mass in the stool. (See picture below) Sometimes she shakes her head. I have checked her ears (clean and not red), her temperature (no fever), her breathing (no wheezing or labored breathing), her feathers (no mites or lice), her eyes (no discharge) and her crop (multiple times a day... it empties within 2-3 hours.) Her belly is not swollen. None of the other girls are sick BUT two of them are showing looser-than-normal stools, but only in the daytime... nighttime poops are all normal. Oh, and they were wormed in December. What am I missing?
