Male or Female? According to egg size

post #1 of 5
Thread Starter 
Some people have mentioned that if the egg is larger it is a rooster and smaller eggs are pullets..
Is this method accurate?

Not at all! Only on day 5 of incubation is when the reproductive organs form. I beleive its 50% determined by inbubation temp, and 50% chance! However, there is no ACTUAL science to it at this point in time.

Actually, just as with humans, it's determined by which sex chromosome the embryo gets at the time of conception. Unlike humans, however, it's the chromosome donated by the female that determines the gender, not the male.
