I asked someone at the feed store today and they suggested 'Terramycin Antibiotic Eye Ointment'
I put some of that on him today, and it seemed to help with the tearing/discharge for a while. The discharge is light yellow, its not A LOT but it just gathers into a little blob at the corner of his eye. The other eye seems fine.
Its not very dusty or dry out there, but maybe its just allergies?
