I believe I would go with Tylon 50. It is an injectable, but they do have water soluable. Tylan 50 injected into the breast meat 1 time a day for 3 days. I believe the dose for adult birds is 1/2 cc. I use a 20 gauge needle because the medication is so thick. You do know that there is no cure for Coryza. You can treat it, but there is no cure. The bird will always be a carrier. If you have no intentions of adding any other birds to your flock then you should be ok. Just watch the rest of the birds closely. Seperate the infected bird now. Keep her seperated until she is 100% better. Goodluck.

I also found this for you:
I have seen this many times before. The underlying causes are many. Things such as E.coli, Pseudomonas,Coryza, Bronchitis,etc.
I would Nasal Flush the bird using Oxine or Tylan 50 with sterile water. I would then apply either eye drops or eye ointment to the eye several times daily.
DIRECTIONS FOR TREATING SINUSITIS WITH SWOLLEN EYES
NASAL FLUSH USING TYLAN 50 OR LA-200
USING 12 CCS OF STERILE WATER ADD 2 CC OF TYLAN 50 OR 1 CC OF LA-200 AND THEN FLUSH EACH NOSTRIL( USING A SYRINGE WITH THE NEEDLE REMOVED ) WITH 3 TO 4 CCS TWICE PER DAY FOR 5 TO 7 DAYS. THE BIRDS HEAD SHOULD BE HELD DOWN SO AS NOT TO SWALLOW TO MUCH OF THE TYLAN SOLUTION.
FOLLOW THE FLUSHING WITH VET-RX SQUIRTED LIBERALLY INTO EACH NOSTRIL. DO THIS AFTER EACH FLUSHING.
USING THE EYE OINTMENTS IS A CRITICAL PART OF GETTING THE SWELLING TO GO DOWN. USE THE EYE OINTMENT EVERY 2 TO 3 HOURS DURING THE DAY IF AT ALL POSSIBLE. YOU SHOULD USE IT AT LEAST TWICE PER DAY. START IN ONE CORNER OF THE EYE AND LAY DOWN A SMALL STRIP OF THE EYE OINTMENT FROM ONE CORNER OF THE EYE TO THE OTHER CORNER OF THE EYE.
IT MAY ALSO BE HELPFUL TO FLUSH THE EYE ONCE PER DAY WITH AN OVER THE COUNTER HUMAN EYE WASH THAT IS BORIC ACID BASED AND THEN PROCEED WITH THE NASAL FLUSHING AS DESCRIBED ABOVE. THE EYE WASHES ARE READILY AVAILABLE IN ALL DRUG STORES.
IT MAY BE NECESSARY TO USE MORE POWERFUL ANTIBIOTICS TO CURE THIS SWOLLEN EYE PROBLEM. IF YOU ARE NOT MAKING PROGRESS , PLEASE CALL ME SO THAT WE MAY DISCUSS YOUR SITUATION AND MAKE ANY NECESSARY CHANGES.
TYLAN 50 OR LA-200 - 2 TO 3 DROPS DIRECTLY INTO THE EYE TWICE A DAY FOLLOWED BY THE EYE OINTMENT TWICE PER DAY FOR 5 TO 7 DAYS
CILOXAN EYE DROPS GIVEN AT THE RATE OF 2 TO 3 DROPS IN THE AFFECTED EYE 2 TO 3 TIMES A DAY FOR 5 TO 7 DAYS
Ciprofloxacin Eye drops or Chloramphenicol Eye Ointment available in the online store on this site.
ETA: Not sure if I would do the nasal flush if I was going with the Tylan injectable. It may be to much. Also Baytril is the drug of choice for treatment of Coryza, but the Tylan should work.
