Why do Brown Layer hens lose egg shell color intensity as they age, and how to prevent it?

Direct Answer Summary
The decline in shell color intensity, often referred to as "Shell Fading," is a multi-factorial metabolic consequence of hepatic (liver) fatigue and the physiological aging of the shell gland (uterus). In brown layer strains like ISA Brown or Hy-Line, the pigment 'Protoporphyrin-IX' is synthesized in the liver and secreted by the uterus during the final 3 hours of egg formation. As the bird ages (past 50 weeks), the liver's metabolic turnover slows down, and the ratio of pigment-to-surface-area decreases because egg size increases while pigment production remains stagnant or drops. This biological "Bearish" trend can significantly reduce your profit margins in the Murghi Mandi, where dark-brown eggs command the highest premium.ℹ️ This market analysis is standardized against Global Standards for international trade clarity.
