    Which are the chicks with the white dots on their heads? Male or female?

    Both. They both have the white dots. You're thinking of sexlinks where only the male has a dot. On male BRs, usually the headspot if larger and blotchier than on the female, but not always.

    When my BR's were about 4 weeks old, I could definitely tell the difference between cockerels and pullets. My roos had a much larger comb, wattles were appearing, and their body color was mixed black/white. Also, their legs were completely yellow.
    My pullets were more black in color, and their legs were black on the front part of them. They had very small combs, and no wattles. Maybe I just got lucky, but my determination of their sex was 100% accurate. [​IMG]

    SEX IDENTIFICATION IN PUREBREDS
    BARRED PLYMOUTH ROCKS

    It had long been recognized that the size of the light head
    spots in Barred Plymouth Rocks varied in the two sexes. The
    males tend to have larger headspots and the females to have
    darker colored legs. However, this method has not been sufficiently
    accurate to be of much commercial value.
    Quinn and Knox (1939) attempted to separate the sexes of
    Barred Plymouth Rocks by means of the intensity of the black
    pigment in the down and legs. In different lots of chicks they
    report 83.5, 86.1 and 91.8 percent accuracy.
    Jerome (1939) describes a method of sex identification in
    Barred Plymouth Rocks based upon the regularity of the outline
    of the head spot rather than the size of the spot. Those chicks
    having headspots irregular in outline and scattered in appearance
    are males while the females tend to have headspots with
    more regular outlines. The author claimed an accuracy of 90
    percent or better when considering only the headspot and 95
    percent if the color of the legs was included in the consideration.
    The Canadian Department of Agriculture (Anonymous 1941)
    issues an excellently illustrated bulletin describing the method.
    It is stated in the bulletin that the method “is widely practiced
    in Barred Rock chicks by commercial chick sexers.” Sex identification
    is based upon outline of head spot, color of legs and
    shade of down color. There are several types of male and female
    head spots...​

    Quote:Is a BR crossed with something else automatically a sexlink? ie- I have a mixed EE bantam roo and he crossed with my BR hen .... the chick definately had BR coloring (how I knew it was my BR hen) but had a white dot on it's head. Is it a sexlink therefore automatically a roo?
