I might be wrong, but from where I sit, it looks like she hacked up what is essentially a hairball.
When you said it "had a bit of smell" were you downplaying it or being literal? Usually snake barf makes us gag, but this looks like she digested pretty well, &
this was just mostly leftover hair (w/ slime, of course, which goes with the territory).
Being in shed can slow down the digestion process (both require extra hydration from the snake's body) so maybe that, coupled with the sudden handling, is why
this occurred. I have a feeling this is nothing to worry about.
