Try to keep the fluids going.
Since her crop seems to still be full from overnight(?) she may have a crop issue. Check it again before she goes to sleep (lights out) then first thing before she eats/drinks to see if it has emptied (flat).
Crop issues can be a symptom of an underlying condition like Coccidiosis, worms and internal laying/reproductive disorders. Keep her hydrated, offer poultry grit (crushed granite) free choice and soft food (egg or wet feed). Since you found a thin shelled egg, she may also need some calcium or is having some laying problems. Make oyster shell available. http://www.backyardchickens.com/a/impacted-slow-and-sour-crops-prevention-and-treatments
