What chicken breeds are auto sexed?
Although the Cream Legbar is the best known example of auto-sexing chickens, the auto-sexing class now spans a number of breeds that were developed in the UK: the Rhodebar, Wybar, Barnebar, Brussbar, and Welbar, among others. Auto-sexing breeds also began to emerge in other countries.

How do birds get pregnant?
