Well, I just wanted to let everybody know... I had gotten the bran and didn't see any baby worms. All my beetles up and died the other day. Was all worried about everything.
I decided to go ahead and heat the bran up, just in case there were babies in there. After doing that, while it was still warm (not hot) I dumped the contents of my little farm into another tray, put the warm bran in their tray and then dumped the old stuff on top of the new. As it was sitting there waiting for me to finish the other little pan, I saw movement! I waited to be sure my eyes weren't playing tricks on me (which they do all to often) and it kept moving in a couple places so I guess I have at least 2 or 3 babies in there! I used the handle end of a fork to lift the movement out of the substrate/frass and blew very lightly on it to get rid of the materials and finally got to see a baby wormie! Yay!
Now I just need to keep feeding them til they get big again?
