My duck, Daisy, seems to have an eye infection. It started a while ago where there is some white gunk in the corner of her eye. They free range in the day and it seemed to clear out (as in I couldn't see any gunk). I kept them in their pen yesterday and today her eye is back to gunk in it, as well as I could tell she was rubbing it as she was dirty on that side of her head. So aside from fresh water to wash her face in what medicine would you suggest to clear it out? There are a lot of regular vet's out here to contact but I want to ask the "duckperts" first. Oh and what you normally would pay for the medicine. Some vet's really like to jack up the price and vary from place to place. Thanks!!
