After the third attempt the first batch of grass clippings was finally delivered. This will be an infinite supply of nitrogen and represents a win-win for me and the contractor, who is normally charged for dropping it to the compost manufacturer. This had been bagged and was starting to compost, which gave me the idea that if I can get it fresh I can make silage to feed the chooks. Silage is pickled grass using anaerobic fermentation so you just have to compact it and seal the top. Properly made silage actually smells sweet. The smell you hate when passing the farm is when the process has failed.
