I have a chicken-powered leaf shredding operation for dressing my flower beds and berry patch: I fill a 14 x 3' strip alongside the house with 2 feet of fallen oak leaves and contain the pile with welded wire garden fence. The girls race to it when I let them out in the afternoon and spend most of the rest of the day scratching through and burrowing into the leaves looking for goodies. I sprinkle half a pound of oatseed over the pile, too. They find some of the seed, but a lot of it sifts down and manages to germinate and send up green sprouts--yet another treat! Within two weeks, 4 loads of leaves are reduced in volume to 1 load of leaf bits and chicken poo. My flowers, blueberries, raspberries and chokeberries are gonna be gorgeous next spring!
