Within a Norn egg, information about a the child-to-be is defined as follows:
Carries the genetic moniker of the baby as a token.
A .gen file with this moniker has already been created at conception.
This genome is what is used by the foetus and following creature.
Carries the sex of the baby. 0=random, 1=male, 2=female.
All natural eggs use a value of 0.
This value is used when the Norn is created at hatch-time to determine sex.
Determines if the egg has been picked up or not.
When an egg is disturbed, its timed hatching script will cease to operate,
thus making it necessary to place the egg in the incubator.
