A Game-Changer for Breeders
The biggest challenge for backyard breeders is dealing with surplus roosters, as half of all hatched chicks are male. Auto- sexing chickens, developed in the early 20th century by Dr. Reginald Punnett, were created to provide visual cues to distinguish males and females at hatching. This innovation revolutionized chicken breeding, saving farmers time and resources, and is now available for hobbyists and small-scale breeders looking to manage their flocks more efficiently.
Auto-Sexing vs. Sex-Linked Chicks
While both auto-sexing and sex-linked chicks allow for visual
sexing, there’s a key difference: auto-sexing breeds maintain
their traits across generations, whereas sex-linked traits
disappear after the first generation. This makes auto-sexing
breeds perfect for those looking to create a self-sustaining
flock.
Why Choose Auto-Sexing Chickens?
Auto-sexing chickens offer a sustainable, long-term solution
for small-scale breeders. With stable genetics and
predictable offspring, these breeds provide a reliable way to
maintain visually sexable flocks for years to come.
