Thanks everyone!! I appreciate the advice and reassurance.

We are very glad she's growing!! We didn't notice her pink belly and blue eyes until we had picked her up to weigh her. She is 1187g. She isn't as girthy as she should be for her age, but she is 3.5 feet long. In the 3 weeks we've had her, she has eaten 2 medium rats (9 days apart,) and even her head looks wider.

I have moistened her bedding and since she's in the cold hut I poured a bit of water on the bedding at the door to moisten it inside. With the moist bedding, her humidity spikes to 75/80% and then 24 hours later will be 60/65% and I mist again.
When she's not in shed, I let her bedding dry out and mist in the morning so her humidity spikes to 65/70% and then after 24 hours it's 40/50% and I mist again. (Once I get a front opening enclosure, misting will be much easier and I can do it more often if needed.)

I've wanted a BP since I was 16 and had to wait 16 years to get one so I am in love with her. I'm glad to have rescued one that wasn't getting good care and I hope she lives a long, happy, healthy life. She's so gentle!!! I felt bad that we didn't notice her eyes and had picked her up, but she didn'the even attempt to bite. She's such a sweet pea!!!
