This may sound stupid, but slugs included? I've seen a number of pics where people have them in their egg boxes, but I'm just prone to tossing them out personally.
Excellent catch. You act like a Lawyer finding loop holes. Actually, we don't not incubate slugs. What I meant was anything that is not a slug (i.e. if it looks remotely white), I give it the opportunity to go bad in due time in the bator.
