My 1 1/2 yr old pekin duck has eye issues. See photo. It's 1 eye only. Looks like she got scratched in the lower left side of the eye skin. No problem in the eye. No swelling, no foaming, no watery eyes, no sneezing, no coughing, no drip any where and the other eye isn't effected at all. Looks like it's getting infected. She'd been pilfering through the mud yesterday when I took this picture. All activity seems the same. Lays an egg every day.
Any ideas on what to put on it? Thanks so much!!
