how often a chicken sneezes...whats normal behaviour ?

[spish]

ive noticed here and there when im in the field a chicken will sneeze..quite often after drinking water as if they got it in their nose.
but these past few days ive noticed it more...from different chickens . i dont know if i hear it more because im actually listening for them sneezing (its been on my mind for a while since reading a thread on here about a sneezing chicken which turned out to be really sick and infected a whole flock or something)
theres one in particular that will sneeze a few times an hour..the others just once or 2 times a day at the most...

they have no signs of illness, no weepy eyes, no runny nose, no coughing, no discharge, no wheezing, just a sneeze here or there...... im guessing a few sneezes are ok here and there???

i don't know an answer, but i had some chickens doing the same thing. I thought maybe they had a respiritory issue...put meds in their water, and they stopped. but, i'm not sure what causes it or how much they just do it naturally. ??? hope someone has a better answer.
