I have a hen with a swollen eye, no discharge, just swollen. I noticed she kept her eye closed most of the day on Thursday, but I didn't think much of it as my birds do that sometimes. Anyways, today it was pretty badly swollen. I isolated her and examined her. I pulled a big chunk of what I think was pine shavings out of her eye (couldn't tell for sure because it was coated with eye goo, you know how eyes coat foreign bodies with slime to try to protect the eye, yeah, that eye goo) and rubbed ophthalmic ointment in her eye. It seems to bother her, she rubs her eye constantly like I would expect someone with hay fever to do. Other than the massive swelling, she's in tip top shape. Good weight, very feisty and perky attitude, healthy appetite, desire to preen and continue social activities, absolutely no respiratory distress, and her other eye is clear and healthy. If it were something serious, I would expect some wheezing, coughing, or a runny nose, but there's none of that. Also, she's the only bird with a swollen eye. Do you think she just has an infection from dirt and gunk in her eye?
