I used 30% Game Bird crumbles and I stick a carrot in every once in a while. I made to much fuss last time. My worms have gotten so big and I have beetles this time. Not a dead tub to toss out. I'm using one small show box sized tub for now, but I'm going to need a bigger one, since they are all growing and morphing on me. It's getting crowed. YAY!
