First of all: Welcome
It's sounds like your setup is great and good to go. Your surely did a lot of research.
I'd still like to add a few things:
1. Humidity:
I think your humidity is too high. Unless your BP is in shed, humidity should be around 50% to 60%. Personally I also like to keep it at the higher end and I know that there are some people that will disagree with me but I think 70% is too much. Too much or too little humidity can cause a respiratory infection.
2. Handling:
I know that it's exciting to get a snake baby but I suggest you don't handle her until she has eaten at least three times in a row.
3. Feeding:
Feed the small baby a week after you got her. She needs to settle down first.
Concerning the size: There's this great chart everyone on this platform shares. In your case a small mouse should be doable.
4. Have fun with your new family member and share some photos!![]()
