While in the barn for a little clean-up time, I noticed my two red hens had shoved themselves into the everybody-wants-to-use-THIS-one nest box together. Of course, I left them alone and went about my business. A little later, one of the girls stood up... I saw her take a nice, long stretch before she loudly announced her accomplishment. While Spot was singing, I somehow had the good luck to see Not-Spot (my daughter named them!) reach over between Spot's feet, grab her friend's new masterpiece, and roll it under herself. Spot finished her noise-making, jumped down, and headed back outside. Not-Spot, of course, then finished her business, and promptly followed her friend outside. Apparently it wasn't an 'I want to sit on that one' deal. I'd never seen them do that before (or get in there together to lay for that matter), but it was definitely an entertaining sight. So, my question to the resident chicken psychologists, what the heck was that about?
