Egg quality refers to the freshness and overall condition of eggs, which can be assessed through various factors. Key indicators include the egg's shell integrity, yolk color, and the thickness of the egg white. Fresh eggs typically have a firm white and a bright yellow yolk, while older eggs may have a runny white and a paler yolk. Several factors influence egg quality, including the age of the hen, its diet, and the storage conditions of the eggs. Hens that are well-fed and kept in clean environments tend to produce higher quality eggs. Proper handling and storage can also help maintain egg quality for longer periods.
