Do I Need To Assist Feed?

Hey everyone im in a bit of a problem, a friend of mine worked a reptile expo helping his uncle out. Instead of cash his uncle gave him a baby female spider, he had her for about a week max 2. Ive had her for just about 2 weeks now myself. He didn't feed her im not even aware of the breeder feeding her but im assuming she did at least once before she went away as payment. She just about 8 inches in length weighs in at a mere 62gr and shes no rounder then a small sharpie marker. Her head is the largest part of her body n she doesnt have much on her bones it appears, she looks thin from the top view almost no change as u go down her body width wise. Im wondering if at this point some one you more experienced breeders would assist feed her? or just let her go until she decides to eat. Ive offered pinkie rat pups new born twice now she seems like she has no idea what they are and moves on. So should i assist feed or wait and see?
