Over heated or something else?

Wings dropped and open mouth breathing/panting?? Only noticed this afternoon eating and drinkin fine. Thanks for any feedback as I am concerned for my chicken, Quinn in the middle. Lower 80's temp

Lower 80s is not all that hot, but some chickens are more sensitive to heat than others, and chickens absolutely will open mouth breathe when they get hot. Just make sure they have shade and plenty of fresh water.

I'm not sure what else might cause that.
