Well, the canibalisn was over for a little while, then started back up full force. I finally noticed one day it seemed as though they were teaming up and trapping one beetle in the bottom of the egg crate and picking them apart. I then quit using egg crate and went to papertowel rolls, and haven't had as much as a single leg taken off since. I lost quite a few beetles figuring that out, but now all seems well. I plan to get a new tub of worms soon and get some more beetles going and finally get my population up a little. My first batch or two of worms are still doing well.
