False alarm. I just went out there, and she was dusting in the dust box, now doing normal chicken stuff (peck, peck, peck). The egg came out, although it has a somewhat rough texture. Maybe she was just having a hard time getting it out, or I could have simply overreacted due to lack of sleep.
But I know my chickens pretty well, and she seemed to be in distress. I have never seen one act like that when laying an egg. Rough texture for an egg, I am not sure what would cause that...She is the only chicken that has a name "jack-ass".
