Hi there, one of our golden comets is suddenly not herself tonight. She is weak and bending her head as if she will fall asleep standing up, keeping her eyes closed. She will not eat but is drinking a lot of water with Apple cider vinegar mixed. She is about 8 months old. Her poop isn't yellow, it's actually almost entirely clear liquid. We're new to chickens this year and don't know what to do for poor lady. We brought her in the house out of the cold but she seems the same. Help!
