Not pooping all night is not too good.
I'd work on that crop. Consider going the next step to impacted and give 1 Stool Softener (not laxative) to see if that helps break up what's in there. I just pop the soft gel into the beak and let them swallow it.
Alternatively, you can try a flush to see if that really moves things along. 1tsp Molasses mixed into 1/4cup warm water. She should drink all of this before she drinks anything else. Usually they like the taste and will drink it down. If not, syringe it into her.
It can cause a lot of loose stool (Molasses has a laxative type effect on chickens), so be prepared for that.
I fear she's got a blockage somewhere
