I use a magical pie on one of my adolescent aeridini and instead of being sent automaticly to my stables she stay in the hatchery. Now, i know i can manualy send her to her new home via her profil but i still wanted to warn you about that minor issue in case someone else run into that as well.

For now she is still in my hatchery as i post this despite being adult

From what I understand, for pets that become adults after using a pie, they only get moved to the stables at the next hour, when the script runs and checks for adults to move.
