Often times when people think of having a rooster covering different kinds of hens, that one is going to hatch all those different eggs. Where as one can truly just pick the eggs they want to hatch, and eat the rest. So in your first hatch, maybe you just want the BO eggs. See what kind of bird you get, the next hatch pick another breed. If you know which bird is producing which egg, then it is not that big of deal.
Totally off subject: I have an EE hen that produces the most beautiful color blue egg, however, the egg itself is very poor quality, thin whites, often times sliding completely off the yolk when you go to fry it. I just use these eggs for baking. Question: would this egg hatch?
