Becky,
This is how I do it. Dump out bin on tarp. Wait about 5 minutes to let the worms head to the bottom to escape the light. Then harvest the castings. As you do this, you will find some contrite worms and eggs. All worms and eggs are put in a container.
Keep rebuilding the pile and worms will duck and cover. Eventually you'll have every thing separated and worms and eggs ready for the new bin.
Hope this helps.
S.
