I saw a similar thread that didn't get much response, regarding a young chick. But I am hoping someone is familiar in dealing with older birds, that can at least tell me if I seem to be on the right track. I have a 6-month old Ameraucana hen who has not been opening one of her eyes. She first had this issue a couple of weeks ago. I caught her (she's a VERY shy free range hen), cleaned the gunk that "glued" it shut, and she seemed fine. Three days ago, I noticed she had the same issue -although I am not certain it is the same eye. I caught her then, cleaned it up again, and released her. But it came back and was "glued" shut the next day as well. So I caught her once again and cleaned it again, this time rinsing it out with the saline solution I use for my contacts. Same problem this morning. But she is getting so used to being held from this (and getting mealworms as a treat after each cleaning) that I no longer had to CATCH her. Brought her inside, more warm clean washcloth wiping, more salinesolution, and THIS time I also used some hydrating eye gel that was prescribed once when I had a cornea laceration. This time she seemed much more willing to open the eye when I released her. Its also just the one side, it seems, which leads me to believe it is likely an injury and not an illness or disease. Has anyone else had a recurring issue like this? And do these treatments sound like they will be safe? Also, I have a very large vial of tetracyclline antibiotic. I know they use a powder form mixed with drinking water for chickens. Would it be safe to administer the injectible type into a chicken?
