Two days ago I came home to a sick duck. She is a 9 month old female Fawn Runner with a runny nose and a swollen eye. One eye is crusty and almost swollen shut and the eyeball itself looks sunken. Her other eyelid was ripped and bleeding. I am not sure if it was pecked or she just cut it on something. She has discharge coming from her nostrils, kind of greyish fluid. A week prior I had a few wrinkly eggs coming from some of my chickens. I was thinking it may be some kind of respiratory thing; a cold or conjunctivitis. I needed reccomendations on how to proceed. I cleaned her eyes and quarantined her to another coop. I am giving her eyes time to heal so that she isn't pecked further. I was thinking of doing a round of antibiotic food for everyone. Any suggestions on food or other remedies?
