Sex Feathers

Small and Backyard Flocks November 02, 2012 Print Friendly and PDF

In order to "feather-sex" or determine the gender of a bird by the type and shape of feathers, look for the following: rounded hackle, saddle, and tail feathers on a hen; pointed hackle, saddle, and sickle feathers on a rooster. Males of the Campine and Sebright breeds of chicken are to have feathers similar to the female and are referred to as "hen feathered" breeds. The term "sex feathers" may also refer to the top two curved feathers of the tail of most breeds of mature drakes prior to and during the breeding season.
