We have a chicken that has been on the nest for days. No eggs underneath her. She just sat there. We boosted her of the nest and she walked around for a bit, but then laid down, with her head down. She made her way back to the coop and laid all day on the floor of the coop. This morning, I thought she was dead and when I rolled her over, she clucked softly. Underneath her, I found two eggs from other chickens! What in the wide-wide world of sports is a-goin' on here?
