My colonies are starting to take off again too. When I put them in the new "high rise apt" I split my already small colony into two, so it had a set back for a few weeks. I am going to split each bin one more time so I will have 4 total to fill the "high rise" but I won't split them again for a few more weeks.
My colonies still aren't big enough to feed out, but I really should go through and get out the dead beetles, I thought they would "take care" of the dead beetles better then they have, my plan was to let the live ones do away w/ the dead, but so far that plan hasn't worked.
