mine are good... i don't worry about it... u can keep them allot simpler than most of what u read... i have mine in shoe box size plastic tubes... about twice a week i give them potato slices and they get kitchen scraps (potato peels, carrot peels/ends, apple cores)... every month or 2 i dump the tub out over another tub and sift the chunks out with 1/4 hardware cloth... anything that don't sift gets fed to the chickens... i feed my sugar gliders, turtle, and fish when ever i want to just reach in and get some worms off the top and feed them out... i add wheat bran when its about to run out... when the tub is about full ill sift it out and only add about 1/4 of it back to the tub to start fresh... at this time ill ether make more tubs to sell or just feed it out to the birds...
