Lack of fluids could be the reason she still has food in her crop, so if it's just grain and crumbles, not grass, fluids should be enough to stuff moving again. One can assume that all sick birds are dehydrated, so tubing Corid water and keeping her warm are what I would do first.
I don't want to freak you out, but food still in the crop can also mean that the dying process has started.
