GAAAH! All was going so well, and then I had a little surgery and lost track. When I looked in today, several beetles appeared to be sucking on a wormie. I checked their quarters: almost all frass! So there's a little setback in the colony. My sister made an emergency run for wheat bran and I dropped in zucchini trimmings. They're all over it. Frass is separated out. Wow, who knew I only had to look away for a few days?
