Is that just a crazy coincidence or is there some science behind this? I've been checking them at least twice daily, no eggs. They do free range but hadn't for 6 days because we were out of town so I just asked my father in law to keep them in the run. I let them out for a bit yesterday but was home and didn't hear the egg song. Today, I heard someone singing and my EE wasn't in the run, she was up in the coop. I decided to go check on her and make sure she was alright ( I had no expectation of an egg). As I walked up to their area, she came down the chicken ladder into the run and I checked the coop and found TWO eggs! One, beautiful bluish one, clearly hers and one tiny brown egg (my silkie?). Her egg was still warm and the little brown one was cool. Here's a photo: The top egg is a store bought large egg.
