i set up my new bin 6 weeks ago,,following the instructions on the pack,,so to speak,,which wornt worth the paper they were written on,,but the worms liked them,well it came with a breathable sort of plastic liner and after placing it in my bin,,sort of makes folds,,were small amounts of moisture gather,,well my question is,,every day theres about 5 to 15 worms climbing up the sides ,,there not trying to escape as ive only ever had 1 casualty,,but i have found several cocoons in the folds,,should i just bleave them there,,or put them back in the bedding
