NPIP normally doesn't test for MG/MS/CRD unless you ask them too.
You can call a state vet to get them tested.
I would mostly be alarmed if they showed more symptoms then sneezing, have gotten worse, or had it for a long period of time going away and coming back.
But the only way you will know is if you get them tested or necropsy-ed.
You can call your state vet to see if they will do the testing for you.
You should also look into worming if they haven't been wormed.
Ive heard worms can cause some symptoms like sneezing or rattled/gurgled breathing and be mistaken as CRD.
You can bring a stool sample to your vet and they will test for worms/parasites, only costs about $12.
Worms can weaken a chickens immune system to the point that makes them susceptable to viral, fungal, bacterial infections. Gapeworm can cause similar symptoms as you mentioned (gurling/rattling,) but gapeworm are rare in chickens. Most likely it's a respiratory disease they are dealing with.
Ya i think it is probably a respiratory disease too.
Its just so sad to see so many people getting that problem.
Mine didn't have the worms either but thought since some other people mentioned it, that it may be of some use to look into..
Anyway so sorry your going through this with your chickens
I wish you the best
