My daughter just texted me this picture of her pygmy goat's eye. They were out of town yesterday, and just discovered his eye was like this today. He lives out in a pasture, has a nice shelter, and the only other animals with him are his sister, mommy and aunt and several free range chickens and a turkey. She doesn't think he has poked his eye on something and blinded himself, she says it appears to be some kind of a "growth" on the outside of his eye. Any thoughts on what it could be? Thank you all in advance for any help.
