Hey! My nephs are both adults now, so it's time to pick out the fathers. (Sorry about the general slowness, I completely forgot to save the link for this thread, so it took me awhile to find it, since I looked in the wrong section first.)
Anyway, I believe the following group would work best, you're welcome to pick whichever ones you like, they all could throw the traits you're looking for, so with a little luck, we can get those visible!

Gene 1: (ND) Faded Stripes(carried)
Gene 2: (CF) Blue Dragon
Gene 3: (GI) Floral Henna (more recessive than lucky runes, so you'd get visible lucky runes)
Mutation 1: (FF) Feathered Wings
Mutation 2: (NE) Sun Armor (carried)
Mutation 3: (NB) Essence of Lightning (carried)

2- https://www.sylestia.com/view/pets/?petid=2776091

uh
you do know that you can make all the traits and mutations hidden?
for both the boy and the girl
and then you breed them
and the hatchling should have the traits and mutations that the parents had but were hidden

i actually gave in and bought essences XD but i want to thank you SO much for the help!

No problem! Best of luck with your project ^_^

thanks :) if you want a free finished offspring from them for your help, just let me know....
