Usually snakes have the opposite "complaint" about their hides...if they're too big or open, they don't feel secure. If that's the case (& I can't tell from the photos)
you can stuff a paper towel or more substrate into it to make it more 'cozy'. BPs usually like to feel "back pressure"- so they feel safe that predators can't sneak up
behind them. There are quite a few photos (some very recent) on here of member's BPs that prefer their old hides that ARE too small over the newer, bigger ones
they were given, & they literally curl up with the hide balanced on top of them, as if imitating a turtle (& with most of the snake showing below the hide), silly sneks!
It also occurs to me to mention that snakes going into shed often prefer the cool side of their cage, & from here that appears like it might be the case with yours.
Snakes know (can feel) a shed coming before we can see the evidence. When did she shed last? Clouding is harder for us to see on albino/pale snakes.
