I started by turning over the soil in the two beds that had been chicken tractored already. The first, most recently occupied, bed had a layer of chicken straw and poop over the winter’s leaf mulch. It needed to be turned. The leaves, straw, spilled food, and poop will compact and turn anaerobic if left untouched all winter. It smells nasty and nothing will grow in it come spring. But, if I give the whole bed a rough toss, mixing soil into the organic matter, it will all break down, slowly in January and February and quickly by April. I turned the first bed and then gave the older bed, which had just a layer of leaves untouched a toss as well. All the while, the chickens were having a discussion; they wanted to dig around in the beds themselves. Before I moved on, I let them out.
