This chicken is about 2 months old and about the past 3 weeks or so it has had puffy, watery eyes. No other symptoms. No wheezing or sneezing, eating and drinking, not lethargic, just eyes look sick. I am currently treating with duramycin. Anyone know what this is? This chicken is in with several other chickens, and no one else is sick. All bright eyed and bushy tailed. Doing great. Can chickens get pink eye? Just need some ideas on the causes!
