My ball does the same thing. After eating she does not want to go back in her hide and she would crawl up the side of the enclosure.
This was my first time feeding my baby BP and she seems fine.
I'm sure you have nothing to worry about.

Is this the first feeding for your BP?

If you have not done so yet, you should take your snake to a reptile vet along with a fecal sample and get her and the sample.
