Only thing that has me puzzling is why just this one? Is she a low flock member? Would she be roosting up on a lower level and closer to the stirred up bedding? Since she's already hard to hold onto, checking for any hidden injuries isn't exactly easy. When I need to nab somebody difficult, I corner them in the chicken coop. I close all the doors and flaps except one lower flap, run them in, close it behind them and come in the door. Somebody needs to invent a chicken straight jacket equivalent of the cat bag.
Problem of treating with everything but the kitchen sink is that if someone else comes down with it you don't know what it was and which treatment worked, so no guarantees.
In theory would be the coop clean out - BUT if you had other stuff going on, mice, wet bedding, possibly a predator attack or rooster attention that you didn't see during the day or night, the problem being caused by something we know about rather than don't know about... then it might actually be something fairly simple.
When you cleaned did you clean to the ground replace the bedding and hose out and open up and air out? There shouldn't be much lingering about in the air after that.
She may have been under the weather and hiding the signs, so it may have started earlier than you cleaning out the coop. Perhaps as far back as the molt, since you mentioned she still wasn't laying. Seeing whether she has any other issues going on, vent/comb/nostrils etc unseen injuries or signs of an old injury... and maybe super prone to stress?
All in all, wish I could be of more help. Worming sounds like a good bet, I've had ducks do really weird things while walking broody that looked sick to me. I actually cleaned out beaks and nostrils with droppers and toothbrushes and dunked heads in buckets because I would have sworn there was something stuck in there, since they were open mouth 'panting' (hissing' at me.. in the nicest way possible) and they decided to sit a couple weeks later.
