I noticed yesterday that one of my goats was keeping his eye shut. I thought nothing of it, maybe he had a fly bothering him or there was something that irritated it as he was just rubbing his head on me. Today, the eye is a little runny with a little crusty yellow around the edges and he is still holding it closed. When I try to open it, he just keeps all the lids tightly shut. He is acting pretty much normal otherwise. Should I rinse with saline? Use a topical antibiotic, something like neosporin, or do I need something different? I am not quite sure how to tell if it might be pink eye or if he just got something stuck in it.
