Pullets breathing weirdly

[AnimalGeek23]

We noticed, tonight when we were putting them back to roost, that some of our 7 B.O pullets had their mouths wide open and throat bopping like a frog. They made weird clicking noises, too, and one would rub their beak against me. Should I be concerned??

What was the approximate temperature in the coop?

Are they breathing heavily this morning, any eye discharge, tail bobbing, or signs of lethargy?

Yesterday was warm, so we put a small fan in the inside of the coop. It was about 79 degrees Fahrenheit, I think. They seemed normal this morning, but this usually happens later in the day. Are they overheating?
