Chicken mating process

naturally a hen will experience a period of laying eggs when it has entered the maturity period of the chicken's reproductive organs, even without the need for a male. It's just that the eggs produced will not be incubable because there is no fertilization of the egg by sperm in the female reproductive organs, the egg without fertilization is called infertile.
In order to produce an egg that can be hatched, of course a rooster is required to mate as a sperm producer, which will then be fertilized by a female parent to produce eggs. Then the eggs are incubated until they hatch for 21 days
