Windows Missing barn animal (Ostrich)

[potat-mom]

My fully grown ostrich disappeared. Though I kinda neglected to pet my animal for two days because I was chasing Qi Loved Gifts quest deadline. On the second day, there was green rain. I'm not sure at which day my ostrich vanished but it also disappeared from my animal list. I do let them free roam and I play in the Forest Farm. All of my other farm animal (barn & coops) are still there.

Help? Or is my ostrich gone forever?

Do you close the barn doors at night?
