Describe briefly the processses of egg formation in poultry.
Egg formation in poultry starts with the release of a matured ovum or yolk from the hen's ovary. This ovum then moves to the oviduct, where it is surrounded by various layers of albumen or egg white, forming the egg's egg white part.
The ovum continues to move down the oviduct, where it then passes through a shell gland. Here, the eggshell forms around the egg white and encases the yolk. The shell is made up of calcium carbonate and provides a protective covering for the developing embryo.
Once the egg is fully formed, the hen lays it and the egg passes out of her body through the cloaca and out of the vent. The whole process takes around 24 to 26 hours and then the process starts again.
