I have some active border collies that love to herd the roosters around the farm. lol
In the fall I let the pigs into the garden to eat any leftovers and work up the ground.
Then I clean out the barns and place wheel barrel loads of spent straw/manure into the garden.
I sprinkle the tops of the piles with grain and turn the chickens in.
The girls scratch and fling the piles of straw all over the garden trying to dig up more grain..................SO I do not have to spread it around myself.
