I've got these eggs:
Chimchar
Shieldon
Cranidos
Misdreavus
Stunky
Charmander
Skorupi
Riolu
Spiritomb
Aipom
Piplup
Chikorita
Gible
Torchic with fire blast
Phione x1 hatched
Phione x1 unhatched
Is it possible you can hatch a caterpie, yanma, venonat, or nincada egg? Or maybe you have a butterfree, yanma, venonat, or nincada? Maybe you could catch a caterpie.....none of those eggs interest me. Just these common bug types I listed.
