2 of my 4 pullets began laying on August 26th at 29+ weeks old. So far I have gotten 41 eggs total from both of them, but sadly, i have never heard an "egg song" from them. They just go up into the coop when they need to lay an egg and come back out and go about their business, no sound. I hope my other 2 will sing to me when they start laying. They are now 27 weeks old and I am thinking they are brown leghorns. My first 2 are mixes.
