I have a rooster in with my hens and am certain I'm getting some fertilized eggs. When you crack open a fertilized egg, how can you tell it is fertilized? Is it OK to eat the egg just as it is? I gave eggs to someone and they said most had been fertilized and that they removed something before eating the eggs. Is this necessary or what? Thanks so much. Am a little concerned about how others will react to some fertilized eggs.
