I found this on the web: When you breed chickens, the male chicks ALWAYS receive their genetic information found in the breeder hen's chromosomes. However, female chicks can't acquire traits from the breeder hen. Therefore, remember that when a hen with certain special characteristics is bred with a rooster without it, all the male chicks will receive it but not the females. Pullets usually are just like their father, while all males end up just like their mother. While the quote is unclear, the article refers to these "special characteristics" as sex-linked traits. Some examples given: nakedness, barring, silver color, and albinism. I also think that some feather development is sex-linked. Are there other characteristics that are sex-linked? As an example, let's consider the Black Sex-link resulting from a Rhode Island Red father and Barred Rock mother. The result is a pullet that is black with some red in the neck and a cockerel that looks like a barred rock with a few red feathers. So, these males are not "just like their mothers" but pretty close. The reverse mating, a Barred Bock father and a Rhode Island mother will not produce the reverse offspring (males black with red necks; females that look like barred rocks), will it? A little primer for me or a pointer to where I could find a bit more than the very basics online would be appreciated. Thanks.
