@JBarstool: a single pot is good too , all depending on which kind of material that you had, if it is high enough than it can serve as a compost bin in situ (the finished compost should go directly onto the beds)
@Zoë:yeah, might be too small for kitchen waste. (but the attract fruit flies part, it is covered up with soil so no worry. still not big enough for kitchen waste, it sounds like a job for a proper compost bin)
@Sally: thanks Sally. Chicken manure disappear real quick in the pots, sometimes I found fat earthworms in them while checking. Might be the wetness in the pot attracted them.
