On top of the newspaper bedding there’s a very thin layer of food scraps, then a covering of soil plus worms.

I’m using tiger worms (red wigglers, Eisenia fetida), originally found via freecycle. Plain old New Zealand earthworms are not good for this kind of composting.

is it something we should worry about. i started thinking of mange, worms etc. she’s had two of her shots so far. she’s about 3 months old. no symptoms of illness
