Sorry about your chicken.
The hardest thing in diagnosing is to understand what is the main disease and what are secondary problems.
Are they still sneezing? A lot? Any seem to have difficulty breathing? Any other symptoms you notice? Birds will hide their weakness, so it takes careful observation to notice if one is not feeling well, as they mask their symptoms. Often we don't notice until they are so far gone, they don't have the strength to fake it anymore.
Was her crop full or squishy? How about the others?
The vent looks like she had a yeast infection (thrush). That usually starts with crop problems, but what caused the crop to stop working well is the bigger problem. I am wondering if they have a virus (sneezing) that is creating these secondary problems from having low resistance.
PS. I would still try try the corid.
