Yes the Vetericyn or Terramycin would be from many feed stores. Sometimes with the Terramycin, you have to ask for it since they keep it locked up because it is in a small package.
I would get some Vetericyn eye wash or the eye gel. If you can't get that, then use saline to clean her eyes, and use some Terramycin eye ointment twice a day. I hope her eyes are okay, and hopefully she will recover.
