Serious or not so serious: Worms balling up can be a sign the worms are sick or are getting ready to crawl. Do something a.s.a.p. (However, sometimes worms will ball-up after they've been shipped or if there's noise or vibration near-by. Usually, after a few days they will sort themselves out into happy individuals.)
