Humidity Rate And Feeding

[allergenic]

Good morning, I'm new to the forum and although I've kept monitors and other large lizards for almost 20 years, new to snakes and specifically ball pythons. I went ahead and searched prior to posting.

I purchased a CB 16inch female BP from a reputable breeder and read up on husbandry requirements. I went ahead and chose a locking 31QT flat long plastic tub and burned rows of ventilation holes with a soldering iron. I originally used newspaper as substrate, an UTH and large water dish on the warm side.

Unfortunately, humidity is at 90%.

I immediately took the snake out and burned 4 more rows of holes in the top (as ventilation is a humidity killer), moved the water dish to the cool side, changed the substrate to aspen bedding.

Still at 70%. Is this too high? From what I've read, ideal is 60% with a hide box humidity of 70-80%.

I like the ease of cleaning I've found using the tub, but I'm wondering if you guys have run into this at all. The humidity is high enough there is condensation on the sides.

She also ate 3 times in a row, and has refused her last 2 feedings, I'm assuming due to stress involved in changes to her housing. I've read not to be alarmed unless it's over a month, but wanted to double check.

Thanks for any help.
