Why can I not hatch a Modest Porygon?

Question

I am breeding a modest porygon with a modest ditto and a naive porygon. But I bred upto 50 porygon, got a docile shiny. But still no modest porygon. Please help me!( In fire red)

Answer 1

This is probably because you haven't put an Everstone to the Modest Ditto you're currently using to breed with your Porygon.
Everstone passes the holder's nature to the child.
