Sexing day-old chicks lets the farm feed and manage each sex to its own growth curve. Males and females differ in feed intake, growth rate and target weight, so separating them improves feed conversion and flock uniformity.
For layer operations, early sexing removes males so that cage space and feed are spent only on productive hens.
Commercial Pullet Brooding & Rearing Cage Specifications
Rearing pullets with uniform skeletal frame development and high body weight uniformity (CV < 8%) requires specialized 3-tier and 4-tier brooding-and-rearing battery cage systems.
Unit cages measure 1200mm (L) × 1200mm (W) with removable virgin plastic chick floor mats (12mm × 12mm aperture) during weeks 1 to 4 to protect tender foot pads. Partitions feature narrow vertical spacings with height-adjustable sliding door baffles to prevent chick escape.
Brooding temperature is maintained via indirect space heaters or under-cage hot water finned pipes (33°C–35°C at day 1, stepping down to 20°C–21°C by week 5). Feeding is automated via traveling hopper carts operating at approximately 6 m/min (~6 m/min).
