Since our laying chickens get to roam wild and free wherever they want, we are hardly putting them to work in every way we could. Sure, they make manure compost and lay eggs, but we haven’t asked them to kill sod for garden beds, or put them in a tractor for deliberate fertilizing. They make mulch for me, though.
All I have to do is feed them twice in the same place, by scattering their breakfast grain in a grassy place. They are so vigorously committed to finding every last crumb that they tear up the grass, it dries, and I collect it with a rake. Clean, soft, dry garden-ready mulch. Maybe with a little bit of bonus chicken poop. Could not be easier.
