I have a golden comet hen. I do not know her age. I can tell she is sick but I have no idea where to start with healing her. Her symptoms started with a fallen comb. Then a "fairy egg" and diarrhea. Runny green and white droppings. Her vent is very gross, from the diarrhea. Its sticking to her feathers. Her tail feathers and her head are tucked in. She is very lethargic. And today I haven't noticed her eating or drinking like usual. Has anyone experienced this in a chicken? Any ideas on how to treat or do I need to find a vet for her? Thanks in advance.
