After awhile you learn to recognize these things that chickens do are just everyday normalities that chickens do.
Humans yawn and stretch, does that mean we're doomed with some dreaded disease? We sneeze without having a cold or allergy symptoms, is that the onset of some nasty contageous flu bug? You get the picture; it's part of our daily lives and part of chicken lives as well.
I'm with Dawg. In a word, RELAX! They sneeze due to dust, pollen and even chemicals in new plywood. They stretch their beaks open and necks up to dislodge a piece of stuck food, etc. Don't go to the worst case scenario.
If you really think something may be wrong, separate the bird from the others and observe for 24 hours without medicating at all. You'll probably find nothing is wrong.
Use normal caution in exposing your birds to pathogens by not allowing other chicken keepers to go into your coops/pens, not buying birds from just anyone and when and if you do buy them, quarantine away from the flock for 4-6 weeks to mitigate the risk of bringing in a carrier bird. Just be sensible, but don't make yourself nuts!
