Chicken Wiki

Sunbathing is a common behavior in chickens. To sunbathe, a chicken will usually lay down on one side in a warm, sunny spot, often spreading out one wing, and sometimes spreading out a leg as well.

Sunbathing is usually a group activity, with many chickens participating. Due to the pecking order, higher-ranking birds will chase lower-ranking chickens away from the best spots, forcing them to find a new sunny spot.
