The crop should be mostly empty in the morning. If it is not, it is not working well. It depends on how full it is if there is a real problem. If it is full, then give her fluids and a little yogurt and egg. Hold off on feed or whole grains. Massage the crop several times a day. Try giving a tsp of mineral oil, coconut oil or okive olil in food. They will eat pieces of cold coconut oil pretty well.
