Chicken Hissy Fits - Repost

I have 2 broody hens (for non-chicken owners broody hens want to hatch eggs) that I take off the nest a couple times a day.  Each time I do, they make this funny trilling noise and pick up straw and throw it around. They remind me of hissy fits on a chicken scale compared to us. They are fine, go drink water, fluff their feathers to cool off, and run to join the rest of the hens. LOL.
