A head count or rather weight estimate of the worms revealed that the population has more than doubled to over a 1000 worms now. Whilst sorting the vermicompost and worms I came across many eggs which I saved and also quite a few centipedes, needless to say they didn't survive the cull.

sorting through the worm bin
I found lots of these stalks which are from the end of bananas and found that the younger worms absolutely love them. i had assumed that they wouldn't like them too much because they're so hard when they go in the worm bin but when they're like this you can understand why they love them because of all the fibrous material contained within it.
I decided to re-organise the worm bin so that they're was hardly any soil in it and that it was comprised of newspaper and cardboarding shreddings and food. This way I will get a more accurate calculation of just how much vermicompost they can produce. The vermicompost from the worm bin that has been harvested will now be used to grow more food (see next update!)
