  i knew I had just read something on this.....   found this -   A study in Australia (Australian Journal of Agricultural Research 11(4) 664 - 672) has shown that eggs stored at 40 degrees Fahrenheit (rather than the recommended 60 degrees) hatch out more females than males. However storing your eggs at colder temperatures before hatching doesn't actually change the ratio of male to female eggs. It has been shown that the male embryos are preferentially killed off by colder storage temperatures, while the female embryos handle the chilling better.
