The two chief methods of sexing chicks are feather sexing and vent sexing. The male eminence is solid and will not disappear upon gentle rubbing with one's thumb. Most males have a relatively prominent eminence, most females have none. A cross between a fast-feathering male and a slow-feathering female results in offspring where the female chicks have primary wing feathers that are significantly longer than the coverts. If not obscured by other coloration controlled by other genes , the chicks can accurately be sexed with little or no training.

With Barred Rocks, the males tend to have a large, distinct white head spot and yellow feet, and the females have a smaller, less well-defined head spot and darker feet. Some are effective only with certain breeds or crosses, while others are universal.

Most males have a relatively prominent eminence, most females have none. The sex-linked slow-feathering gene can be used for crosses where the sex of the chicks can be determined at hatching time by the length of the wing feathers. Successful development of this technique depends on the capability of the students and their level of experience. The Keeler Optical English or Chicktester Japanese machine features a blunt-ended telescopic tube, containing a light. The male eminence is solid and will not disappear upon gentle rubbing with one's thumb.

In-ovo sexing[ edit ] Automated systems to determine the gender of the developing chick long before hatching have been announced but not widely deployed as of July The sexer inserts the tube into the evacuated cloaca and with the help of the light can identify either testis or ovaries. An S female mated to an s male will produce offspring where the females have a darker, buff down color, while the males have a lighter, whiter down colour.
