Why aren the worms moving up from the lower levels into the top working tray?
A. This situation can arise in two ways. First, you may be adding new food too soon before the worms can eat the previous food. This will result in a lot of uneaten wastes being distributed throughout the system and general reluctance by the worms to migrate upwards while they can still access material lower in the system. Before adding new trays, stop feeding the worms for at least a week to ensure that all existing food in the lower tray has been eaten. Worms will then move up to eat from the surface as this is their natural behavior pattern. Secondly, you may not have waited for the level of worm casting to pass the support ribs on the inside of the tray before adding the next tray. This will create a gap preventing the worms from reaching the top trays.

Secondly, you may not have waited for the level of worm castings to pass the line on the inside of the tray before adding the next tray. This will create a gap preventing the worms from reaching the top trays.
