so, i got the idea that maybe reading a "how to hatch" book (ex. how to hatch a zaphao egg, how to hatch an otachie egg) would increase that players chance at finding said egg, hatching it (at any age), and hatching a rarer color. i also had the idea of creatu ageing in their eggs. like, 15 day old egg=15 day old creatu. 

The book idea is nice.

thanks for the input. personally, waiting for them to grow up sucks for me (im way to impatient) but thanks!
