Do hens need cocks to lay eggs?

Female mammals need to mate with male mammals to reproduce, while birds can lay eggs without mating. So hens can lay eggs without mating with roosters.

But if the hen doesn't mate with the rooster, the eggs laid are sperm-free, and the chicken can't hatch and can only be eaten by humans. Therefore, if the chicken farm raises laying hens, not breeders, such hens do not need to mate.

Eggs before fertilization are called azoospermic eggs, and chickens cannot hatch. The egg after mating is not necessarily a fertilized egg. If you can't fertilize because of pathological reasons or the time doesn't match, the eggs will be laid soon, and you can't hatch chickens for the eggs after mating.

Only eggs that have been successfully mated and fertilized are useful to hatch chickens.
