The fertile egg vs abortion is not the same thing. Fertile eggs start growing a chick when the incubation starts. Wild turkeys lay an egg a day for 12-14 days and will not sit on eggs til last egg is laid. The chicks will all hatch within 24 hours. So you cannot compare a human to a fertile egg. So what came first the chicken or the egg? The chicken.
