I think my Barred Rocks are slightly better layers, but my Buff Orps lay slightly larger eggs, at least one of them does. Although, Lexie lays a very large, very dark egg for a smaller BR hen as people who have received her eggs can attest. She laid through almost her entire molt and refused to quit. I think you should have the best of both worlds! Wait, didn't I send you some of Lexie's eggs?
