The worry is that she's in the humid hide or that she's sticking her head out partially? Sounds to me like she's just out hunting a bit, my young ball seems to be always head out watching and waiting in case I'm going to drop a fresh meal in. Snakes can stay in feeding mode for a while after eating and young ones are all about the food normally. I don't fuss over which hide they stay in as long as temps are correct, they'll find where they need to be.
