Well, of our 4 Barred Rocks, we had one (Mimi), that was not laying and the lowest on the rung of hierarchy....always last to get to the treats and picked on if she tried to get in on "their" goodies before they were done. She is the sweetest one of the 4 too....(of course). After 8 months old, she finally decided to get in on the "fun" and has laid 3 eggs so far....we KNOW it's her, cause we were getting 2-3 eggs a day the last 3-4 months, and this week we have had 3 FOUR egg days! Way to GO Mimi!!!!
