The ratty breath is probably due to the crop not being able to drain properly due to the possible obstruction.
I haven't mentioned another possible cause for an obstruction. It's still too early to jump to this conclusion, but a reproductive tumor could cause the same symptoms.
I'm still hanging my hopes on this being a stubborn egg. Last year, my twelve-year old SLW was backed up with such an egg, and it ruptured and she suffered a prolapse on top of it all. She was every bit as sick and wrung out as your hen. It took her nine days to pass the obstructed egg material, and she made a full and quick recovery once that crap was finally out of her. Her crop also was backed up. She's still alive and happy and doing well.
Be patient and there's an excellent chance this hen of yours will recover from her ordeal, also. Just keep doing what you're doing. Offer her feed and some egg to keep her strength up.
