In poultry, males have two sex chromosomes (ZZ) while females have one (ZW).
Several breeds have been developed—often by crossing a barred breed with a non-barred breed and then stabilizing the line—to achieve these results:
Can be bred together to produce more autosexing chicks. autosexing
The majority of autosexing breeds rely on the .
Females typically have a dark, sharp "chipmunk" stripe; males are paler and often have a diffuse white spot on their heads. In poultry, males have two sex chromosomes (ZZ)
Known as "German Kennhuhns," these show very distinct down colors at hatch.
Result from crossing two different breeds (e.g., a Rhode Island Red rooster and a Delaware hen). Their offspring will not breed true; if you mate two sex-links, the next generation will lose the predictable color markers. Performance Benefits Females typically have a dark, sharp "chipmunk" stripe;
refers to specific purebred poultry that hatch with distinct visual differences between males and females, allowing for immediate gender identification without invasive methods like vent sexing. Unlike "sex-links," which are first-generation hybrids, autosexing breeds "breed true," meaning their offspring will also possess these same identifiable traits. Core Mechanism: The Barring Gene
