I have a white and a barred rock, a gold-laced and a silver laced wyandotte, and a buff orpington that were hatched on June 2. That makes them 25.5 weeks old. They have not repaid all my treats and cooing with any eggs. I showed them. I bought a dozen and a half eggs today. Since I am now well stocked on eggs, I am expecting them to start up any day now.
