Ok I'm thinking this chicken stuff is way over my head. How would I know the eggs I have eaten for a week if from the chosen rooster? An egg is an egg to me when I am eating it. And yes, we can divide the coop, Irishrovr. Thanks for joining in. I'm thinking I will need all the help I can get.
It takes awhile for an egg to fully form. Here is a picture of some eggs taken from a dead hen to help you visualize the process. The rooster fertilizes the egg early in the process so it will be a week or so before you know for sure that the hens you sequestered with the roo are going to bear his little chickaroos.
If you eat the eggs for a week (or two) instead of collecting them you will make sure none of the other rooster's progeny are going to be hatching.
