Traversing vertically

The worms are going up and down through the holes in the tray bottoms. They are looking for a nice place to make a nest. The bottom tray is too hot due to the fresh food I put in there a couple of nights ago, the second tray has a lot of coffee grinds (but I did spy a worm swimming its way through them!) and the tray above that has food that is nicely composing and doesn't look like food anymore, but doesn't resemble castings quite yet either. That tray is currently the most habitable tray for them I believe.

I bought my original batch of worms about 2 months ago, and I don't have many castings yet, just bits here and there. It is exciting to see everything transform, I can't wait to see how the next few weeks go!
