My barred rocks are 25 weeks old today and have been laying for just over six weeks. For the past almost two weeks, they have all been laying an egg a day. Anyway, my smallest girl has been laying a double yolker daily and although I know there isn't anything I can really do to stop that, I'm wondering if its harmful to her? They have very healthy shells, membranes, and gorgeous eggs but it seems like the poor girl is working overtime! Any input is appreciated!!
