Possibly a combination of feeling brave enough (after about 10 days of settling in) to check things out, & yes, likely hungry. When did she last eat?

But without more info, it could also be due to other things, such as inadequate hides (?), nervous because of excess activity nearby, or handling-? (best to wait until snake
has fed about 3 times at normal intervals before you do any handling). So while it's likely just hunger, you have to consider the whole picture & we don't have that info to
answer you accurately.
