One of my hens (Production Red, about 1 year old) can't seem to open her eyes more than a slit. I can't see any discharge (from her eye or anywhere else), inflammation, or anything else that seems out of the ordinary. She's all puffed up like she's cold (it's currently 33 degrees) but trying to move about, though she's either not interested or can't figure out how to get food or water without her eyes. I don't see any abnormal looking droppings at this point, but she was in with her sisters overnight so if there were any, they'd be mingled in. I'll keep an eye out and update if I notice anything unusual. I tried rinsing off her eye with a bit of water because the eyelid seemed a bit dry, but it hasn't had any noticeable effect yet. Anybody have any other ideas? Unfortunately, we cannot currently afford to take a $5 chicken to the vet, but she's a good layer, so I'd hate to lose her. Thanks in advance for any help!
