Weird things only poultry people get.

Ok, let me clarify, the gender of all multicellular organisms is determined by weather the of offspring get a y or x chromosome from their father (they always get x from their mother) if a child gets a x chromosome, its a girl, y its a boy. In chickens I suppose y chromosomes are more sensitive to cold, and often dye off. I think being mammals, the temperature is more easily monitered, where eggs are entirely dependent on incubator/mom. In nature, mother hens actually hatch more hens than roos, usually, and stressed hens hatch more hens to. Tiny science lesson, yes, I played a lot of attention to Jr. High science.
