Black Sex Links are a breed cross using Rhode Island Red males and Barred Plymouth Rock females. The male chicks have a white spot on the top of their heads and can be separated from the solid black female chicks when they hatch. This cross, which is used in commercial layer operations, is an efficient producer of large brown eggs. They have excellent livability, and hens from this cross weigh about 5 1/2 lbs. and can be salvaged for fowl meat.
