keep in mind that they only eat their weight, and when it's cold/stressed/new home they eat less
but think about it, 1000 worms don't weigh much.
Freeze leftover fruit pieces, then thaw, then mash, then dig a small hole in the middle of your wormbin, plop the fruit in, cover, and presto, the worms will eat like a mofo.
BUT don't feed them until your bin is clear of the last food, or you'll have issues, reason is worms have clear favorites when it comes to food, and they'll abandon the other food when you add the fruit. And the old food will rot, and smell.
they LOVE fruit.... grapes, melons, pears, apples, avocados, bananas, etc.
all those when they go bad, let em get reaaaal ripe, and then chuck em in the freezer.
only need a full freeze to burst the fruit open on a microscopic level, which essentially is cutting out a LOT of the feeding time for the worms.
