Also, you mentioned this is Ziggy's new home- what did he live in previously? The dimensions you gave above for his new home are quite large for a BP- and many prefer cozier homes because they feel safer. When they feel safe, that's when they eat & thrive, so it's possible that the trouble you're having is because he feels "lost" in his new home.
It's also just very confusing & scary for a snake- they don't understand where the home they knew disappeared to, even if the size isn't overly large. But when you house a BP in a large enclosure, it usually means you need to make it feel cozy- by adding multiple hides & other things to "clutter" it (like branches, driftwood, fake plants, etc.).
