g'day wylie,

not real whiz on worms, but never haerd that casting contain eggs they
could of course. but it is winter now so the worms will be dormant and
any eggs in the soil won't hatch until next season when it warms.

also they don't call them night crawlers for nothing that is what they
are by name and nature, worm farmers generally steer clear of them as
they tend to want to crawl out of the farms and away.

you'd do better with tigers or red wrigglers, but might need to wait
until next summer.

those dirt balls could be just where worms have come up to the surface
to feed? they may not be castings as such.

With peace and brightest of blessings,
