Their semen fertilizes the egg made by her ovary, and after that her body coats it with its protective shell.
Though conception takes place within the feminine’s human body whenever her egg is fertilized, the chick hasn’t technically been born. A process which can take just a few seconds or several minutes after the egg receives its shell inside the female’s body, she expels it from her cloaca. The oviduct that is fleshy inside her cloaca expands and agreements to stop the egg from being contaminated by feces or other bodily waste which will cling to your cloaca, therefore the egg is set neat and sanitary.
