What poultry science does know is this. A hen tend to lay a particular shape of egg, with reasonable consistency. We who keep hens note this with some frequency.
What poultry science also knows is that, since the sex of the chick is determined by the hen, AND, that SOME hens tend to reproduce a disproportionate number of male eggs, while some other hens tend to reproduce a disproportionate number of female eggs. Strange as it sounds, apparently, hen A lays mostly male eggs while hen B mostly lays female eggs. Can we extrapolate from that a workable system? I am quite skeptical.
Obviously, nature balances this out in a way that if one takes 1000 fertile eggs and hatches them, as the hatcheries do, the result remains approximately 50/50. That is what poultry science seems to know, at this point.
For absolute certainty!!!!! If a hatchery could predict the sex of the fertilized egg, they'd do it. It is not economical to hatch, and then have to destroy, all those unwanted males chicks. They do this costly method because they, who would stand to gain the most from a workable system, have yet to find one.
