I activated a hibernating egg a couple days ago with no problem, hatched it into a Lykos. I have two more hibernating eggs in my inventory, plus a liquid deviance, but cannot use them. When I click on both the eggs and the deviance, I only get the prompts 'sell / give / destroy'.  

NM, thanks to arete, I figured it out!

Have you gone to the Craft And Construction tab, and crafted the activated egg?

:facepalm:

Can ya tell I'm still a newb? XD

Thank you!
