Well she's still here. The clicking has lessened. She's still sleeping most of the time, but we were able to get quite a bit of electrolyte solution into her yesterday evening. She was a little pasty again this morning but cleaned off pretty easily. She's not getting any worse, so I'm a little hopeful.
I'm so glad to hear that. We just lost a chick to similar symptoms. He lasted about a day after we noticed he was sick. My friend found him asleep on his back and when I turned him over he just flopped onto his face. He never even opened his eyes, he was so weak. I had my dad take care of him.

I hope yours does better.
