I'd be asking the source if she was bred (ever?) so you know if these are likely just slugs or not. I'd keep her especially quiet & un-handled, so that she doesn't
tense up & retain eggs, feeling there's no good place to lay them. I'd ASSUME there's more to come...& just in case it's fertile, don't roll it around...I'd incubate
it quickly & cross my fingers...At some point you'll want to gently have her crawl thru your hands to feel if there's more, if you don't see any more eggs laid.
And good luck!
