I hate to be nonsuportive of my worms but a few of them are just confused. How do they manage to half drown and half dry out? I have found maybe 10 this way over the past few months. Is the tiny bit of bin drainage acidic or with no oxygen? It is the same half a cup of water I have repoured over the top of the bin from the drainage for the past few days. I have damp cardboard but they find an area with none and half water rotted and half dried corps.
