Rubber egg shell left inside

I have two Rhode Island Reds who started laying in November. Up until 10 days ago one of my favorites laid daily. I noticed a large portion of an empty rubber egg shell hanging from her vent and pulled it off. I didn't know where the rest was but figured it had passed. Since then she hasn't been eating much -just drinking. Her egg laying has ceased. So, based on advice I read on this site I got out the rubber gloves and proceeded to extricate a mass that had built itself around what looks like the rest of the rubber egg. It's been two days and she's still not eating her pellets. She'll take a little yogurt now and then but I can't even persuade her with cackleberries or meal worms. Her stools are still very loose but at least they're white and green. Is there anything else I need to do? I want her to get back to her "old self" soon. Our temps have been in the 90's so I'm sure the heat isn't doing anything to help.
