I have a hen who is about 2 years old who seems sick. She is walking and moving less and seems dazed. As I watch her, I notice her 3rd eyelid frequently blinking closed over her eye and then opening. She is less aware of her surroundings, but seems somewhat aware. Our cat approached and she raised her feathers to look larger and pecked at the cat once, but this is a much more diminished reaction than she normally would have. I have looked her over and can find no wound. Her droppings are more liquid than normal. She mostly stands in one spot with looking downward and dazed. I separated her from the flock 2 days ago. She is not eating as much, but she does eat and drink. She seemed a little better yesterday, but worse today. Any ideas? Thanks in advance for any help!
