Black Star hens are a cross between a Rhode Island Red or New Hampshire rooster and a Barred Rock hen. Both sexes hatch out black, but the males have a white dot on their heads. Pullets feather out black with some red in neck feathers. Males feather out with the Barred Rock pattern along with a few red feathers. Black Sex-Links are often referred to as Rock Reds or Black Stars. They are planned crosses, which are hardier and more productive than their parents’ respective breeds. The Sex Link Hybrid is the result of crossing two purebred standard breeds. This hybrid makes for very vigorous chicks, rugged brown egg laying hens and good cockerel fryers.
