Hello.
I just saw your cage pics, and your setup looks great.
Of course, that means less than nothing. You said your monitor is using all the hides you give it and that is the thumbs up you need. Good job!
Your diet sounds good too. I supplemented my baby BRN's crickets because she wouldn't eat pinkies until older. (I forget if you were using any extra calcium.)

You got the wrong idea with the arboreal comment. I'll try again.
A cage is a box. It is not arboreal. Put in a lot of branches, and its still a box... with a lot of branches. I had that arboreal thinking too, last year. "If I add more branches, then its arboreal!" Ummmm, .. no. If its 10 feet tall, then its a tall box, with a lot of branches. See? Better to just forget that term, you aren't going to get it, in a box.
What need is addressed, by them being so arboreal in the wild?
How can you fit your box, to fit your rudi?

These are questions I am asking myself, too.
Best of luck. Post pics of him as he grows. I LOVE BRNs.
