how to??

check out feathersite
http://www.feathersite.com/Poultry/CGP/Sex-links/BRKSexLink.html

some traits are sexlinked, they come with the male chromosome W
A rooster has two of these male W chromosomes
He passes one W chromosome to each of His offspring
a hen has a W and a Z chromosome.
She passes one or the other to each of her offspring
The ones that get her Z will be hens.
More importantly to your question, these girls get Their W from their father
If for instance If mom is Barred and dad isn't
the babies will get the non-barred W gene from dad
all the girls will will be non barred
the boys will get the dominant barred W gene from mom and will be barred
RIR rooster to BR hen gives barred boys and black girls
