Care for sick chicken?

[aaron3]

Hey everybody, 2nd time posting and first time chicken dad. I have 8 girls all about 5 months old, none are laying yet. My silver laced wyandotte has what appears to be an eye infection. Her left upper eye lid is swollen and her right eye is crusty and oozing clear liquid. She is acting very lethargic and somewhat limp when I pick her up. She is isolated in a dog crate away from the flock, I put some animal antibiotic cream, Terramycin, on her eyes earlier today. She is eating and drinking still from what I see. Anybody dealt with something similar? Anything else I can do? Thanks for the help!
