Oxytetracyline isn't a very ineffective antibiotic, and Tylan only treats a few bacteria, and it must be given at least twice a day, so it's quite possible that you need to modify your treatment program.

So you see foam or bubbles in the eyes?
It's so hard to know what's going on. It could be a respiratory illness like Infectious Bronchitis, Mycoplasma or one of the many other illness chickens can have. Moldy bedding, dusty feed/bedding ammonia odors and poor ventilation can also cause some respiratory distress.
Since you notice watery eyes, flush them with saline to clear them. You may want to take her off shavings and place her on puppy pads or towels, to see if bedding (environment) is the cause.
If you feel it's respiratory illness you can try giving injectable Tylan50 to see if it helps - it can be given orally or by injection 1/4"deep in the breast muscle. (Dosage of Tylan50 is 1cc per 5lb) - you need to weigh her. You can give it 2x a day. Keep in mind antibiotics will not cure respiratory illness but can help with secondary infections - respiratory illnesses are contagious and birds are usually considered carriers, even if they recover.
Without more symptoms, you may want to try something like VetRx first to see if there is any improvement - this might help if the cause is environmental.
Taking her to a vet for some testing would be your best option, this way you know what you are dealing with and get the correct treatment. Keep her warm and hydrated. Offer some poultry vitamins in her water.
Keep us posted.
