It's amazing what a different twelve days can make to a compost pile.
I suspect the chicken manure was largely responsible for the fast
heating and the equally fast slumping in this case. No matter what the
cause, by the time our most recent cold spell hit, the pile was no
longer breathing out visible hot air and it had also lost about a third
of its bulk. Time to regroup a little bit.
I didn't exactly turn the
pile. Instead, I forked up some of the outer perimeter that had sunk
down to below critical mass for composting. Now the pile is about as
tall as it was before once again, but it's more pyramidal and
considerably smaller in total volume. I'll be curious to see if it heats
up again or just slow cooks for the rest of the winter.
