I used to, but don't anymore for a couple of reasons. Mainly complaints from my wife and her blender :angrywife: and second, just hand crunched is too coarse to break down in any sort of reasonable time frame. Like, less than a year. Whatever the source, it needs to be as fine as flour to actually work/be effective. The whole surface area thing.DD, am I being silly to blend my egg shells?
Since I now use a peat based bedding, adding pulverized Dolomite lime is easy, works like a champ, and keeps the wife happy. Keeps the peats pH right for the worms also. Straight peat is too acidic for them.
Not silly, but a lot of effort when a bag of dolomite is only $4.50/40lbs.
