I have several 21 week old chickens - Dominiques, Polish, and Silkies. One of the Polish started squatting yesterday and I just heard one of the silkies singing the egg song! Unfortunately I didn't see an egg when I ran out into the coop. They free range so I figure I might have to go egg hunting later today. How close do you think we are? I am on my last few store bought eggs and I would love to show DH that the chickens are finally laying! I am very excited and yet impatient!
