I used vermic this year and got a 100% hatch rate...

It's not hard to mix...being able to see a properly mixed batch in front of you helps a lot. A lot of people make it WAY too wet...it should almost feel like "did I really add any water?" In other words, dry to the touch.

That, and I feel like eggs were meant to sit in something - all the success of people using the no substrate method obviously contradicts that - but it makes me "feel better" knowing that they are sitting in something.
