I dunno, the Jubjub entry says:

''When a human man approaches Jubjub's eggs before they hatch, it may cause mutation to the eggs and turn them into a slime monster known as Humpty Egg, with a body capable of mating since birth. Being a mutant race, Humpty Eggs will lay normal Jubjub eggs, although they will have a higher chance to mutate into a Humpty Egg than eggs laid by Jubjubs. ''

It says that the man being close provokes the mutation, not that only mutated eggs react to the presence of men...

But you may be right about the embryo sensing that their father is already claimed.
