DD have a lot of leaves in the backyard left from last Fall. Good idea--I think I'll bag them up this weekend and give them to the chickens.I don't have a run, as my birds are free ranged, but I always advocate for those who do to incorporate a deep litter system in the run, at least a foot thick, of a variety of materials that will allow air and water exchange in the mass. No more muddy runs, no more stink, no more flies and a great place to compost kitchen scraps, garden refuse, etc. Healthier environment for chickens.
