Anyone ever heard of a Black & White sex link? My son is showing a Black sex link this weekend at a poultry show. The bird next to his looks like a Barred Rock (with a tint of red in the neck), but they claim it is a sex link. They actually thought it was a black sex link because whoever they bought it from told them. The show judge said it is something new called a Black & White sex link. Can't find anything on the internet. Just curious if anyone has any info on these.
