How do you revive a dragon hatchling dragon cave

You go to actions and press revive. This rarely works. If it revives it used to become a zombie dragon, but they deleted all of them due to some complaint. Now I have no idea what happens. Good luck though. I recommend trying it at exactly the hour or at noon/midnight. Experiment.

To prevent hatchlings from dying, check if they are sick (view them and read below) and check the guide here for cures: This is for hatclings and eggs:
