Needing advice! First time chicken owner- yesterday I noticed one chicken has foamy discharge (sorry no photo of foam) from one eye along with this sore on left side of the eye (see photo). She is generally acting normal- have not noticed nasal discharge, sneezing, or coughing. Or any other noticeable sores… is this fowl pox? A cold? It’s only from one eye. And my other 6 hens of the same age show no signs. Grateful for advice!
