You never did tell us how her crop felt - does it have anything in it this morning?
Have you introduced new chickens within the last 30 days?
Breath that smells bad, along with watery eyes and the other symptoms you describe, I would say she has a respiratory illness.
Could be Infectious Coryza, Mycoplasma, Infectious Bronchitis, ILT or another illness that chickens can have.

If she is still in respiratory distress, I would be careful getting fluids into her, but she needs to stay hydrated.
With this being so close to Christmas, I don't know if you can see a vet, but that would be best. You can try giving her Tylan50 which can be found in most feed stores like Tractor Supply. Dosage is .25ml per pound of weight given orally 3 times a day for 5 days.
Since there is a bad odor, she may have more than one thing going on or it could just be respiratory illness. Sour crop comes to mind, canker too but respiratory illnesses like Infectious Coryza is supposed to smell bad. If it's Coryza, the Tylan50 may help but a sulfa drug is a better choice of treatment. You can get that from your vet or order it online.
Let us know how she's doing.
