Thabks Susan, I don't deep liter as we have three small houses due to infighting. Also I admit our birds are just pets, they are good slug eaters but very fussy on leftovers! The cheeky madams.
Thanks for the advice on composting the Guinea pig bedding. I can't put it all in at once as we are restricted by size here, we only have a small box for the worms, they get veg peelings and tea and coffee too. I run bokashi as we have two small kids here too so get random leftover food bits but I love the way it all works anyway. The bacteria must be good I figure. Plus I'm adding the contents of the bokashi.bins to the allotment compost heap now and when the beds are finally dug in they will be topped up with bokashi regularly.
