I bought a bantam rooster at the chicken show in Lucasville last weekend. His eye looks like a catorac is above the pupil. I purchased eye terramycin and I have been putting this in it. It doesn't look any different? I also have him on Sulmet aulfamethazine Sodium 12.5% antibactorial drinking water solution. How do I know if it is an eye infection or something like a catorac? We have no chicken vets in our area. Any suggestions?
