I have 5 Plymouth Barred Rock hens who are 25 weeks old. The smallest of them has an eye problem. Several weeks ago, I noticed that she was closing her left eye several times. I did not worry too much as I assumed it was perhaps pecked at or the result of an accident. It does not appear to have affected her eyesight. The right appears normal. None of the other hens have been affected. Recently, I took a closer look when she was on a roost and the sun gave me better visibility. There was a clear film over the eye and very slight bubbling. The eye almost doesn't seem to be as 'open' somehow. Her appetite is good, as is her mobility and behaviour. Occasionally she will just stand there with her eyes closed. I don't see any other signs of injury or problems. There isn't a single chicken vet where I live. I went online and paid for some ver advice. This was the response:
The foamy appearance in that eye is usually associated with either chicken coryza (Haemophilus paragallinarum) or avian mycoplasmosis and both of those infections can remain in a carrier state in spite of administering the proper systemic antibiotics to our chickens. If Brave Heart has remained otherwise well, I would see how over the counter Terramycin* ointment administered to both of her eyes thrice daily for a minimum of 10 days affects her. Terramycin contains oxytetracycline - an antibiotic of choice for addressing either of the infections I mentioned.

My feed store has never heard of Terramycin so I ordered some online and it should be here soon. I am not seeing any symptoms of coryza or mycoplasmosis, though, of course, I could be wrong! I have noted no sneezing or coughing. What concerns me other than any discomfort she may be experiencing, is why it doesn't go away. When the medication arrives, how on earth does one apply it? No way I can apply it three times a day as I have no one to help me. Does this condition sound familiar to anyone and how does one apply it correctly? Any over the counter medications that anyone knows about? Thanks
