In rural areas, after laying a certain number of eggs, a hen chooses to hatch it into a chick. Once, when the hen was hungry during the hatching process, she clucked and asked her owner for food. Only two eggs were left in the nest.
Then the cats heard the hen's cry and knew that it was gone, so they took their babies and took over the hen's nest. The cats lie down carefully and do not break the eggs.

The hen's egg is just an egg cell that develops, and it will lay eggs if it is not mated with a rooster, that is an unfertilized Yunying egg, and the egg born after mating is a fertilized egg. The eggs to be applied to the chicks must be fertilized.

This question. Female mammals need to mate with male mammals to reproduce, while birds do not need to mate to lay eggs. So hens don't need to find a rooster to mate before they can lay eggs.
However, if the hen does not mate with the rooster, the eggs laid are infertile eggs and cannot hatch chicks, but can only be eaten by humans. Therefore, if the chicken farm raises laying hens and is not a breeder, such hens do not need to mate.
Eggs before fertilization are called inseminate eggs and cannot hatch chicks. The mating egg is not necessarily a fertilized egg, if it cannot be fertilized due to pathological reasons or the time does not coincide, the egg is about to be laid, and the mating is only for the egg that cannot hatch chicks.
Only eggs that have been mated and successfully fertilized are useful and can hatch chicks.

The hen ovulates every 25 hours or so, only the left ovary and oviduct develop, and the fertilized eggs are not released from the hen's body before reaching the critical level of incubation (24).
Hens raised at home lay eggs all year round. After about 20 or so, it will stop for a while. During this time, the hen does not lay eggs, but lies in the nest, as if hatching eggs.
After a few weeks, the eggs were laid again. This is the case of chickens raised at home. It is not clear about the chicken farm.
