This polish hen is a little over a year old. She has been lethargic since yesterday and is squatting down but not in the penguin-like stance. Tonight we noticed she also has some heavy breathing. No other flock members are exhibiting any symptoms. She isnt very handleable so we havent been able to do a physical inspection. She hasnt been eating or drinking much since yesterday. I was able to entice her to a little bit of cottage cheese (her favorite) but that is it. I’ve attached photos of her abnormal droppings. She is not laying eggs, but all our adult hens stopped laying a month ago due to decreasing sunlight and/or molting. We did have an active mite infestation a few weeks ago that we treated using elector psp. Please help!
