My Production Red; Mcnugget, has been laying double yolkers for 2 months straight, since the day she has started laying. I hear they grow out of this but ITS BEEN TWO MONTHS! Is this normal? I also want to hatch some chicks from her this spring, but is it possible if she keeps laying double yolkers? I am actually quite amazed at my hens. Every single on of them hasn't missed a single day since they had started laying and they are handing out pretty nice sized eggs.
