>>2307035Mix it with leaves or woodchip or whatever and turn the pile every once and awhile until it looks like dirt.
Or mix it and leave it there for a few years itll do it itself. Personally I live in a similar climate and I build a big covered cchicken run fill it high with some brown stuff and let the chickens shit and dig in it. I turn it once or twice a season and take out the compost twice a year.
