Hello!
I accidentally moved an egg to my stables, and then moved another I got later. How do I move them back to the hatchery? Will they still hatch in the stables? Also about how long does it take eggs to hatch?
Thank you so much to anyone who can help!

You can't move an egg back to your hatchery, but it will hatch in your stables so it's not a problem.

It takes an egg 3 days (72 hours) to hatch after its bred. When the progress bar in the "Genetics" section of the egg's profile page reaches 72/72, you can manually hatch the egg to give it a tiny stat boost, or 24 hours after it hits 72/72 it will hatch on its own :)

Thank you so much for the info! ^~^

yeah, the only difference an egg being in the stables makes is that it can be publicly sold- pets in the hatchery can only be privately sold.
All eggs and hatchlings show up in the nurturing grounds regardless of if they're in stables or hatchery

Oh, Im sure that will come in handy, thank you!
