Hitherto unwitnessed behavior

At least by me with my chickens. I have read that other chicken keepers have noticed their hens putting straw or leaves or shavings on their backs before or after laying an egg. This is the first time I’ve seen one of my hens. I think this is Sunrise. She has a yellow band and a green band on her left foot, and a smaller comb. Not very effective camouflage if that was the original advantage, but a very interesting example of gene driven behavior.

By the way, I found Cockatrice on a nest recently, so now all 12 of our hens are laying. We are getting anywhere from 3 to 7 eggs a day, despite the low light hours of winter. Summer egg counts will be interesting.
