I have a RIR, Peggy, who is 2 years, 11 months. Peggy started laying at a regular age, and was a strong, consistent layer with quick molts. A year ago, we integrated some younger pullets into our flock, and Peggy was very aggressive, so we put her in an adjacent cage alone for about two weeks while we integrated them. The flock integrated well after that, and Peggy returned back to the top of the pecking order as soon as we re-introduced her into the coop. But she didn't start laying again. Two months later, we moved the chickens when we moved homes. And while all our other hens returned to their normal laying patterns about two months after we moved, Peggy hasn't laid for about a year, since we first put her in the adjacent cage while integrating the flocks. Two years old seems really young to stop laying, and I wonder if it's possible the trauma of putting her in the adjacent cage, and then a move, could have caused her to stop laying permanently? We haven't changed anything else-- food is organic modesto mills, occasional black sunflower seeds and oyster shells, and the pecking order has been settled for a long time, no one is picking on Peggy since she's at the top. Any ideas to try to get her to start laying again?
