Ya iv seen some babies in my frass drawer...they drop from the beetle drawer directly to the worm drawer...I figured the babies will have plenty to eat with the other adult meal worms but they seem to inevitably drop down past them to the last drawer.....that is the frass drawer....im going to try getting the babies to fall in the pupa drawer (place it directly under the beetle drawer) this will avoid me shifting through the frass trying to find the little wigglys, not that im disgusting by the frass it just a pita doing so..... I dont know I havent optimized the setup yet... I might just add a dedicated baby worm drawer....I have a bazzilion pupas now......
