chickens need to mate first,they also need a sperm of the rooster before laying an egg so it will fertilize the egg that the chicken will produce otherwise they will just lay blank/unfertilized eggs...
the eggs we normally consume is unfertilized (the white and the yolk) .even if the hen incubate the egg it will not hatch to a chick
now i feel like i am talking to kids, coz didn't we learn this on reproductive lessons in grade school? ( ̄∇ ̄")

ohh srry learned it in biology class, chickens are the common examples so its hard not to not remember but honestly it's almost the same as for humans when it comes to how it happened the difference is they lay eggs and people birth humans..
fun fact: an egg is basically in simplest term - the hen's menstruation
This way he can keep his child but does the eggs really contain chick because it said that the eggs that came naturally doesn't have anything inside isn't?
