VetRx is a natural herbal formula for relief of cold / respiratory symptoms . I would not put it In the eye, but instead try rinsing with saline and then apply terramycin antibiotic eye ointment, in the eye.
I have vet rx and i like it for my chickens when they have a mild respiratory symptoms...
I remember your thread about her eye, and things like apple cider vinegar in her water bucket and /or saline rinse and terramycin ointment were suggested I think... Which treatments have you tried?
