Casa--
By any chance does the hen's face have a sickly sweet smell so it would be Coryza? Denagard is powerful for treating CRD caused by Mycoplasma, but if she has Coryza she'll need something else.
Of the three birds of mine with CRD (which I think was caused by MG, Coryza & other problems, too), only one ever developed an eye problem, and it was from Coryza (I could tell by smell on that hen) & just in one eye, along with mucus in mostly one nostril, as well as gurgly breathing. My hen's eye was quite watery/runny, though, & Penny's eye looks pretty dry.
Terramycin ointment cleared up my hen's eye with just a few days of treatment, & you can buy that at IFA for $17. But I'd make a wild guess that a little powdered tetracycline medicine mixed in a little water might work, too. Though it may be that the powder wouldn't be safe around eyes--dunno?
