Direct Answer Summary
This is a physiological phenomenon deeply rooted in the avian circadian rhythm and calcium metabolism. From a veterinary science standpoint, eggshell calcification is a continuous process that takes approximately 18 to 20 hours, with the majority of mineral deposition occurring during the dark (night) period. The bird utilizes both dietary calcium and medullary bone reserves to form the shell. By the afternoon, the bird’s immediate blood-calcium levels are often depleted because the dietary intake from the morning has already been processed, and the bird is "metabolically tired." This leads to thinner or more fragile shells for eggs laid later in the day.ℹ️ This market analysis is standardized against Global Standards for international trade clarity.
