Swollen/inflammed nostril? (with photos)

UPDATE: There is some crusty/snot/mucus in that swollen nostril. Used some sterile saline to wipe nostril, I'm concerned about illness as opposed to sometbing stuck in her nasal cavity. Should she be separated?

I noticed one of our baby bantam steele eggers has some swelling around one her nostrils. I didn't see crustiness/discharge or anything yucky, she's been acting completely fine. Her eyes look good and face doesn't appear to be swollen. I'm of course worried it could be early sign of sickness but I didn't find anything that looks like what she's got going on. I haven't yet looked her mouth, will do that tonight.

Could she have gotten pecked there?

You known, I wouldn't rule it out. I know babies are curious and they peck at each other's faces, feathers, feet, etc sometimes. But usually just lighty, I haven't really observed these chicks pecking with real intensity or force?
