Temperature and egg storage duration play an important role in determining the shelf life of eggs. This study aimed to investigate the effects of egg storage temperature and egg storage duration on the quality of eggs produced by commercial laying hens raised under free-range conditions. This study employed a 2 × 8 factorial experiments arranged in a completely randomized design. The first factor was egg storage temperature, and the second factor was egg storage duration. There were five replications for each treatment combination. Data were collected on egg weight, percentage weight loss, egg shape, and egg quality. The results showed that the interaction between egg storage temperature and egg storage duration significantly affected yolk height, yolk diameter, and yolk index (P < 0.05). Egg storage temperature significantly affected percentage egg weight loss, albumen height, and Haugh unit (P < 0.05), whereas egg storage duration significantly affected percentage egg weight loss (P < 0.05). These findings indicate that refrigerated storage slowed the deterioration of egg quality in eggs produced by free-range laying hens more effectively than storage at room temperature under actual conditions.
