It's getting pretty cold here and my flock loves wandering our yard. They faithfully return to their run each night and then to their coop where they are locked in for the night. They are eating much less crumble (and love foraging thru the leaves and such. We sprinkle their scratch near their home to encourage them from wandering too far and still give them fresh treats. I assumed in cold weather they would eat more than usual. In the late fall and winter what are they eating out in my yard?
