There is another possibility. Do you have hen grit in the coop? Sometimes a hen (like my Maggie) will gorge on hen grit before being ready. Hen grit can contain some very large pieces and occasionally you get an individual with a 'thing' for it. Most payer feed contains grit and oyster shell anyway. Or you can offer grit that has been strained of the large bits (coffee can with holes in bottom to catch rocks).

and see if this applies to her. More on fibrous impaction too, which you can solve if you are persistent. I wouldn't risk a flush except as a last scenario, it's easy to kil the hen if she aspirates into her lungs.
