Recently one of my Barred Rocks developed a swollen eye (or at least the area around the eye is swollen). It happened very rapidly, swelling to it's current size...which is VERY large. At first I thought she either got pecked or poked her eye on something in the coop. However, there is no external abrasion which would indicate that kind of an injury. I am wondering now if maybe she doesn't have a tumor??? Besides the fact that she looks as if she's got two heads she perfectly fine. She eats, drinks, squawks, lays eggs, etc. Does anyone have any experience with this?
