It looks more like an eye injury to me and not coryza, I have included a description for you, please stop freaking out....
Coryza (previously known as things like a cold or roup) is caused by bacteria called Heamophilus paragallinarum, which primarily attacks the upper respiratory system, including the nasal passages. Swelling of the face, wheezing, sneezing, nasal discharge, conjunctivitis (including bubbles at the corner of the eye), eyes glued shut, and open-mouth breathing are some of the more common symptoms. And they may appear singly or in various combinations. But the most telltale symptom is the unmistakable odor that is generated from the nasal discharge. Once youve smelled this odor, youll identify it every time. Additional symptoms unrelated to breathing can be a drop in production, reduction in fertility, diarrhea, and a decrease in water consumption. Although not as common, if rales are detected, then it is safe to assume that the lower respiratory tract is involved as well.
Coryza can be chronic in nature or acute, and youngsters tend to suffer from less severe cases than the adults. The acute cases are spread rapidly and death can occur within hours to days of the first symptoms.
See what I mean, it does not sound like that at all, only one eye is affected and you also are not complaining of cold like symptoms. Do you happen to have a metal feeder? There was a thread about chicks getting cut on the sharp edges, I would think more around that. I wouldn't use the pink eye drops, I have no idea what is in it and you could do more damage, I would just flush. Let us know how she does.
