First ball python! Could use some guidance.

What do you recommend for measuring room humidity? I worry because I have her enclosure in the same room as my chinchillas. The chinchillas require constant AC so I'm sure the humidity isn't the highest (although it's a basement so I'm sure there is still a decent amount even with the AC on). I've just been misting the tank and draped a wet towel over the top to try and increase the humidity. My petco guage does say it's 55-65%, but I realize that's most likely not accurate (and when I mist the humidity gauge goes up to 80%).

Also, I found her out this morning completely stretched up along the side of the tank with her nose at the screen, and she just sat there.. is that normal, or is something wrong (like her trying to get to the heat source)?

That's normal. Especially for a new snake in a new home or after rearranging its home. When you startle them they will freeze in place because they are trying to hide and hoping you can't see them.

You by a weather station for your home but most you will find are Accurite. I still think for the money they are pretty good. The best gauge of your humidity is your snake. After a shed you will see if the humidity was good and the longer you keep them the better you will become at being able to read your snake.

I promise you humid hides will make your sheds great.
