Chick Brooder. It is a known fact that hens lay eggs. However, what is not very well known is that hens can lay eggs with or without the presence of a rooster. For the eggs to be fertilized, the hen and rooster must mate first, and this process must occur prior to the formation of the egg.f the hen has not mated and she lays an egg, then that egg is unfertilized. Note, however, that the embryo of a fertilized egg does not undergo any change or development once it is placed inside the fridge. It has also been said that a hen lays fertilized eggs for a week if it has mated even once.
