Hi
@BR-L 
Welcome To BYC
I'm sorry you're having trouble. How is your chick doing?
Does she still have the white in her eye and the swelling?
Any other symptoms - discharge/mucous from the nostrils, coughing, sneezing, lethargy, etc.?
What course of treatment, if any, have you tried.
To me it looks like she has pus in the eye - if she were mine I would flush it with saline and see if the white glob would come out with a little gentle pressure and working it out with a saline dampened q-tip. After I got all out that I could - I would apply either Vetericyn eye gel or Terramcycin eye ointment (or similar ophthalmic ointment) 2X a day.
Watch the eye for any more pus/discharge and flush, remove and reapply ointment daily.
There are many reasons for having pus/discharge in the eye, a peck or injury, debris/food in the eye and respiratory illness are some of the most common causes.
Keep us posted.
