Resting Birds

I found a group of chickens resting behind a log of wood. The birds appears to have fed up already after a long hunt for meal then decided to chill out here for a nap.

Two were squatting on on of the woods while two were busy cleaning up themselves.
A little shutter and one looked up in suspense. I think was a rattle from birds that fled by.

On realizing it wasn't anything serious, it goes back to its cleaning.
