I don’t understand chickens

The temperature is dropping, the wind is blowing, and the flock is huddled in a feathery ball in the outside run. Huh.

Hens huddled together in the cold

The coop is open, and draft-free, just in case you are wondering. It is their choice to be in this place at this moment. I don’t understand chickens. As a side note, they did have all their heads tucked down, until I so rudely crunched the leaves and rocks trying to take a picture.
