Older spooder

I just bought my second p. Regius from a expo yesterday for 25$, from what I can tell she's an adult and mybe gravid? The vender didn't have much info on her or the others she was being sold with. I believe she might be wild caught though. But im worried because she is having alot of trouble climbing which I've heard happens when there older, leading her to only be on the bottom of her encloser. I'm wondering if I should home her in a smaller encloser with more grips for her and too keep eye for an egg sack or if anyone had advice or experience of what to do. I definitely want to keep her and i feel prepared for everything that comes with having babies if she is gravid and the egg says fertile. She's very gentle and sweet just a bit skittish.
