When does the daily water intake cycle peak in brown layers, and how does it correlate with egg formation and ambient temperature?

The daily water consumption pattern of commercial brown layers is highly cyclic and correlates with biological processes. The first intake peak occurs 2 to 3 hours after the morning lights-on signal, coinciding with peak feed intake and metabolic activation. The second, more critical peak occurs in the late afternoon (between 4:00 PM and 6:00 PM), which correlates with the active phase of eggshell calcification in the shell gland and the replenishment of water lost during the day. If water is restricted or warm (>30°C) during this late afternoon window, the rate of calcium transport is impaired, leading to weak eggshells. During extreme summer heat, water intake can increase up to 500% to support panting. Water dynamics are discussed in the Poultry Encyclopedia, water filtration systems, inline medicators, and chillers are sold on Poultry Plaza, current mandi rates are updated on Poultry Rates, and active commercial layer farms are listed on Murghi Mandi.
