Humidity problems and not eating

[Mayj12]

Hello, I picked up a boa 5 days ago. Tried feeding her tonight and she wasn't interested at all. I understand they need a while to acclimate but I figured 5 days before trying would be sufficient. I must admit we did handle her yesterday, would that cause it? Maybe too soon? Another thing I read that It could be caused by husbandry errors. The hot end is at 90 give or take and cool side around 81. So this is where the humidity question comes in, I was told 50-60%. But then i've read 60-70%. I figured I'd shoot for the middle. Going by my digital hydrometer/thermometer it says 58 to 60 most of the time. However I also bought a zoo med one but it's the old school dial ones. It's almost 10% lower than the digital always. I woke up one morning and looked and one said 55% and I was like cool i'll give it just a little mist. Looked at the other and it says 45. Which should I trust on this? Granted one is on the hot side and the other the cool side but that shouldn't matter I'd think. She hasn't shed yet so I can't go by that yet. Back to feeding again, It's 10 days between feeding so I don't think it's too soon for that. She's 2.5 yo according to the dealer.
Anyway, I'm rambling now. I just want to make sure I'm getting it right. I don't want her to be harmed.
