The Nubian doeling that was left with her dam (out of triplet doelings) has runny eyes. Both of her eyes appear to be irritated and she isn't seeing all that well. She is still nursing fine and does get aound but her eyesight is limited due to her teary eyes. Is there something I should be looking for? What is the issue that can occur with the eyelids? It started out as only one eye and now both are irritated. I am not seeing it in any of the other four kids running around.
