I got the medicine and have started to apply it. His eye is bulged out and his other eye is now sealing shut and is for most of the day blind. Anything I can try to help him?
Sometimes it can be hard to differentiate whether the eye problem is bacterial, or viral of origin. Sometimes chicks may get pecked in the eye, or scratch their own eye with fecal matter, and the bacteria can move into the eye, cause irritation, discharge, swelling, etc. If not treated, it can spread. Terramycin contains (Oxytetracycline) which has decent coverage against most bacteria, so I would use that for a few days, as well as flushing the eye, and wiping off any gunk with a damp towel.
If you don't see improvement after a few days with the Terramycin, although it seems unlikely with your case, it's always possible it could be a respiratory infection like Mycoplasma Gallispetcum (MG) which can cause conjunctivitis, of the eye, often accompanied by other respiratory-related problems. MG is uncurable, but systemic antibiotics may help.
Eye problems can often be set on by dusty bedding, and high ammonia, so try to keep dust/ and fecal matter down to a minimum. Make sure to offer her feed, and water often. Vitamins, and scrambled eggs may be good.
