That's a stuck shed she's not going to get it off by herself you have to help her get it off...I wouldn't feed her until you get the shed off.
What I have found that works best for smaller ones is wrapping them in about 4-5 continuous sheets of wet paper towels...Fold her up in it really good and put her in her enclosure over the heat...By the time she works her way out the shed should come off.
