My chicken has a cocked head, and is kinda listless. What's wrong??

[Mystery Peepers]

I went out to the coop this afternoon and one of my chickens (she's about 9-11 weeks old) was walking around with her head cocked to the side and her eyes closed every few seconds. She didn't run away very fast when I walked toward her like the rest of the chickens. What's wrong with her? I looked up her symptoms online, and the closest I found was botulism. But I KNOW it's not that, she doesn't have all the symptoms.
Any suggestions?
