Why does Heat Stress impact Brown Layer hens more severely than White Layers?

Physiologically, brown layer hens have a lower surface-area-to-body-mass ratio, making it harder for them to dissipate internal heat. Additionally, the metabolic energy required to synthesize brown pigment creates extra "Internal Heat Load." During heatwaves, brown layers reach their "Upper Critical Temperature" faster than white layers, leading to immediate panting and a Bullish spike in water intake, which dilutes gut enzymes and turns production Bearish. As a PhD practitioner, I observe that chronic heat stress in brown layers leads to permanent shell gland damage, resulting in "Pale Eggs" for the rest of the cycle.ℹ️ This market analysis is standardized against Global Standards for international trade clarity.
