The auto-sexing Barnevelder was produced by adding the barring gene to a good strain by a repeated system of back crossing. The males are homozygous for the gene and are hatched whitish and grow up light barred.
The females being haplozygous are hatched brown striped and grow up greyish brown. The sexes can be readily identified at birth.
