Two eggs is normal. It happens from time to time. The softer shelled egg will harden up. If you'd left it on the sideboard while it hardened it would have had a flat side. Is she starting to lay after taking a break?

Stool color fluctuates with what she's eaten. It is alright to give her things like fruits and vegetables. She'd eat those on her own if she were out foraging for food. I don't know if dark stool is actually a sign of infection. Maybe someone else will know.

Hey Cuppers,

They do make good pets, don't they?!

Just one more suggestion. Next time, before going to the vet, you might check at the feed store if they have any advice. Often times those folks will give you as good or better advice than a non specialized vet.
