Old school vermiculture (just fyi stuff):

I find that decaying leaf piles tend to be full of redworms,
with a lot more of those than any other kind of earthworm.
The advice that I once read to not put tomato and pepper
seeds in worm bins turned out to be wise (the result of
including unscreened tomato and pepper debris in the
worm food is volunteers from hell when you finally use
the earthworm castings, ie weeds in your containers that
never seem to stop sprouting until frost). I have not seen
any negative effects from including crushed egg shells in
their feed stock (advice that I also ignored).
