We found our chicken outside in the run lying still, lethargic, eyes kinda glazed over. It's been in the low teens here in Western NY. Brought her inside and noticed she has a classic S shaped movement of her neck. It comes and goes. She's not eating and drinking only when forced to by a dropper. I'd describe her poop but she hasn't pooped in the past 10 hours. She is 3 years old and just noticed the weird head movements when we found her this morning. Rest of the flock look fine despite the frigid conditions. We have a red light in their coup to keep the water from freezing and take the bite out of the chill. I've got Penicillin inj and Sulmet on hand. Thanks so much for the help UPDATE as of 9am Tuesday My Buff is looking much better. She finally pooped but was mostly clear water and some white in it. Going to irrigate the crop today, and get some anti-fungal in her Thursday morning UPDATE... Our Hen died last night. She asperated her own vomit back into her lungs and died.
