I have begun to consider the possibility of incubating some of the eggs my hens lay. I know my roo is doing his job because I've been checking for fertilization when I crack them open to cook them. (I learned how to check it on BYC ) My question is regarding double-yokers...I get them quite a bit, but have been eating them. I have also started looking at the yokes to see if both are fertile, but from what I've seen on the last 2 eggs (I ate or gave away the others, before I learned how to check fertility), only ONE of the yokes is fertile. My questions are: Is that how they are all going to be--one fertile & one not? Do double-yokers ever hatch out twins? Has anyone tried hatching out dbl-yokers? Should I not even bother & just enjoy the eggs? Thanks!
