Cornish losing feathers on crop?

[mesz5]

That makes a bit more sense... It's super cold here, and they get crabby inside the coop... This is my first attempt and raising chickens and I get freaked out easily!! Haha, none of the other girls seem to have a problem, so I'm crossing my fingers it's not lice/mites... That REALLY freaks me out!!! Hopefully it's just nothing, but when it gets lighter outside I'll check! (Still dark here in Colorado)
