Sorry about your chicken. Are you planning on getting a necropsy if you put her down? I would suspect possible Mareks disease, but a necropsy by the state vet would be the only way to know for sure. Here is a list of state vets:She’s gotten much worse. She cannot sit up and her neck is twisted around. I’m not sure about her poop, it doesn’t seem like there is much. Likely putting her down tomorrow. Not sure what happened :/
