Their semen fertilizes the egg made by her ovary, and after that her body coats it in its protective shell.
Post-Conception Behavior
Though conception occurs within the feminine’s human body whenever her egg is fertilized, the chick have not theoretically been created. 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 avoid the egg from being contaminated by feces or any other physical waste that will cling to the cloaca, therefore the egg is set neat and sanitary. The embryo matures in the egg, that is incubated by one or both associated with moms and dads, until it offers developed sufficient to hatch and endure within the air that is open.
