I also got puppae very early. Collected them on the tower and after the beetles form, they sooner or later move down. I have the feeling, they are dizzy for the first day, which is no wonder, as they just found themselves in a new body.
After two weeks i moved the beetle tray into a new layer, as some many of my oldest mealworms had either dyed or become puppae. I wasn't quite shure, if i received eggs, since ther were also small pieces from oats etc. However, two weeks later, I have no new mealworms in that layer now and it is getting time to move the beetle inly to the next layer...
Would be nice to receive some official instructions from LivinFarms.
