Polbar
Gallus gallus domesticus
✨ Hauska Fakta
The Polbar was created by Laura Kaufman, one of the few female poultry geneticists of the mid-20th century, who developed the breed during Poland's communist era when scientific poultry research was a rare area where women could rise to prominence in agricultural science.
A Polish auto-sexing egg-laying breed developed at the University of Life Sciences in Lublin in the mid-20th century by Professor Laura Kaufman. The Polbar was created by crossing Polish Greenleg Partridge chickens with Plymouth Rocks, producing a breed where male and female chicks can be distinguished at day-old by down colour — making vent sexing unnecessary. This was a deliberate effort to create a Polish equivalent to the British auto-sexing breeds developed at Cambridge University. The Polbar is a medium-sized, active bird with barred plumage reminiscent of the Plymouth Rock, laying white-shelled eggs. It is cold-hardy and well-adapted to Polish free-range conditions. Though developed as a practical farm breed, the Polbar is now kept primarily for conservation and by enthusiasts who value its auto-sexing capability. Recognised by the EE Europastandard.
