Also, no signs of 'damage' so to speak. Flushed with clean water, will be treating with antibiotic ointment. He's been isolated. Can it be an eye poke or peck or something? I'm not sure when this started, the bird is 3 weeks old.
I've done a bunch of reading so far, looking for opinions. One eye is completely fine. All other 14 birds are good. No mucus or smells. Seems healthy and strong, legs fine, wings strong, active, eating and drinking fine
