Swollen, puffy eyes?

[smornge]

Yesterday I went to check on my chickens and found one of my chickens with a puffy eye. At the time it had a few, small bubbles, but it stopped. Today one of her eyes is almost swollen shut. Her left eye is now fully open and slightly puffy around it. There are no other obvious problems, she is breathing fine. What do you think?

Look into coryza, there seems to be lots of it going around lately.
