Feather & Color Sexing Guide

Feather Sexing Guide

Sexing is done by examining the rows of primary and covert feathers on the outspread wing as illustrated. The wing should be viewed from the top and good lighting is required for those performing this task. The length of the primaries as compared to the coverts is more important than the total length of the feathers when determining the sex of the chick. Provided correct mating, chicks from feathersex parent stock can easily be sexed by inspection of their wing feathers

Males

Males are slow feathering. In cockerel chicks, primaries (2nd row of feathers) are shorter than or of the same length as coverts (1st row of feathers).

Females

Females are fast feathering. In the pullet chick, primaries (2nd row of fea- thers) are always longer than coverts (1st row of feathers). Primaries are longer than coverts.

How to Hold Chicks

The wing should be examined from the top surface, holding the chick, feet down, with the head toward the operator. Fan the wing between thumb and index finger to ease differentiation of feather rows.

Color Sexing Guide

To improve accuracy of color sexing, please observe the following points:

  • Do not try to sex chicks that have not completely dried. Chicks that have been allowed to dry and fluff out will be easier to color sex.
  • Be sure to use plenty of bright light. “Cool white” fluorescent light will be too dim. Use of a 200 watt incandescent bulb is recommended.

Males

Most of the males are pure white

Occasionally they show a slight faint striping on a light ground color

or 2 distinct light stripes with a brown edging

and sometimes one dark stripe in the middle of the back

Females

Most of the females are brown with one light stripe in the middle of the back

Or are uniformly brown

Occasionally they show one broad light stripe with brown edging on a lighter ground color

Or seldom have a brown co- lored head and a generally
lighter coloring of the body
