It blocked its home off a while ago and I know this can mean pre-molt, should I bother leaving pre-killed food in there or just wait until it opens up again?
If they sealed off, then you don't need to. Sometimes they'll open it back up, not always are they molting. Just keep an eye on them and see what they do. And if they have a good size abdomen, even better.
