Can you post some photos of her poop and of her?
When you say she is sick - do you mean that her crop is not emptying?

Look inside her beak for any obstruction, plaques, lesions or canker.
It's hard to know from your description, but I'm thinking she has a crop problem - is it hard, soft, air or fluid filled, doughy, sour, etc.?
Read the following article and let us know which one it is

Also while you are checking the crop, take a look for any lice/mites and feel her abdomen for any bloat/swelling or fluid.

How old she is, what you feed and when she last laid an egg is helpful information too.
