Female chickens (hens) account for around 90% of the breeder flock population, yet males contribute 50% of the flock\u2019s genetic output. Poor male management will limit the production potential of day-old chicks (DOC). To achieve maximum performance, males must develop a large skeletal frame, maintain proper body condition, and sustain mating activity over time.<\/h6>\n
Performance Begins During the Rearing Period<\/h6>\n
Males and females should be reared separately from DOC stage until mating age (21\u201324 weeks), with separate feeding and drinking systems. Grading (size selection) is recommended as early as possible, since approximately 50% of skeletal development occurs within the first four weeks. Achieving a 28-day body weight target of around 745\u2013755 grams will support optimal skeletal development. The lightest males should be culled to create a stronger and more uniform flock.<\/h6>\n
Uniformity is the most critical factor in male management. Non-uniform flocks can create dominance issues, mating ratio problems, and reduced fertility.<\/h6>\n
Males are highly sensitive to limited resources. High stocking density increases competition, dominance behavior, and body condition variation. Male density should not exceed 4 birds\/m\u00b2, while female density may be adjusted to support this target. During rearing, feeder space should gradually increase alongside male growth, and stocking density must be carefully managed, especially after 10 weeks of age.<\/h6>\n
By 15 weeks, the focus shifts from body weight uniformity to body condition uniformity. Male breast condition should be monitored routinely. Ideal males develop from a \u201cSunken V\u201d breast shape toward a \u201cStandard V\u201d as they grow. Poor breast condition negatively affects mating ability, semen quality, and reproductive longevity, while overly fleshy males may experience incomplete mating.<\/h6>\n
Preparing Males for the Mating Period (18\u201322 Weeks)<\/h6>\n
Before entering the production house, final selection should be carried out. Males with short legs, poor skeletal structure, uneven body condition, or physical defects should be removed. At this stage, only about 9.5\u201310% males are needed to maintain balance without causing overcrowding or excessive competition. Uniformity levels should exceed 90% (CV around 6%).<\/h6>\n
