Did someone say that the father/rooster determines the gender?

    I just want to know if there's any science behind the notion that the rooster determines the gender of the chick.

    Did i dream that?

    Actually, in poultry its the female that determines the gender of the offspring.

    Quote:Sorry. [​IMG] Didn't mean to be so vague and expect you to read my mind.

    I had a hatch of black sexlinks. Seven girls, 3 boys. I have 5 barred rock hens and one bo rooster that made these chicks. So initially, i thought that was a good sign that this rooster makes a high percentage of girls. It will be harder to narrow down which barred rocks have a higher percentage of making girls. So i guess i'll just be happy about my high percentage and move on. [​IMG]

    To make it short, I know for sure that in humans it's the father who determines the sex of the baby. I can't imagine any reason to think that it would be any different for chickens.

    As joebryant said, the male is the deciding factor in HUMANS.

    In chickens, it's the female. The male is ZZ while the female is ZW.

    In mammals, the male is XY and the female is XX. Thus, it is the male that determines the sex of the offpspring.

    In avians, the male is ZZ and the female is ZW. Thus it is the female that determines the sex of the offspring.

    However, in the case of the OP, it is theoretically all random - so the sex of the offspring that you got was simply determined by the eggs you chose to incubate.
