UPDATE! So I got all my remaining items and finished the setup. Temps via temp gun are 83.3 in hot hide and 75.2 in cool hide, humidity is still a bit of a struggle as Im used to hot side also being the water side. It is currently at 56%, but luckily humidity is an easy fix.
However the more important news is that from the moment Nezuko settled after I finished with the set up, which only took her 45 mins. She has not wandered once!!! She seems cozy and satisfied with her home for the first time! So I will now give her a week to get accustomed to it then try feeding again! Thank you all so much for your help!
