Tylan50 dose is 0.25ml per pound of weight given orally 3 times a day for 5 days in a row.
IF you can only do twice a day then I would give it at 0.30ml per pound of weight for 5 days in a row.
Below are photos, description and video of how to give oral meds. I like to place the hen on a table so she can stand (easier on my back too!), I drape my left arm over her and pull her to my body and lock her in with my elbow, this allows me to have my left hand free to help control the head and pull down on wattles to open the beak. Right hand gives meds and also helps to control bird and open beak. Takes practice.
Some find that swaddling the hen in a thin piece of cloth or towel helps a lot, if you have the wings captured, then you have a lot more control.
It's possible that she doesn't have respiratory illness and just has eye infection - could be from getting something in the eye, injury (poke/peck/scratch) to the eye, etc.
Keep working on the eye, if you can get photos of what it looks like open that may help. Swelling like that usually always has some pus, so work on flushing, give the tissue some good pressing to see if any pus will arise too.
