My guess is that she will shed soon. I know that Winry is about to shed when she starts spending more time in her hide. Usually she pokes her head out of her head several times throughout the evening except when she is going into shed. When she's in the process, I don't see her at all for a few days until she's done.
Try to keep humidity between 60%-70% for a few days and I'm sure she will shed soon![]()
