I was wondering for the people who put sand in their runs, do the chickens still have plenty of stuff to forage for? Mine have eaten all of the grass/weeds in the area their coop is in now, we built this coop to be a tractor but have talked about possibly leaving it stationary too. My run has a bunch of flies and it is driving me nuts. The run is just sitting on the once grassy area of the yard we put them on last weekend when we moved them in. I clean the poop out of the coop daily but since it is in the run it is all over whats left of the grass & in the dirt and I dont think raking it would be very effective. This cant be healthy for them, I dont know what else to do. Im switching out their hay bedding for pine shavings tomorrow (just bought it) the hay just doesn't seem to do much to keep the flies & smell out for more than a day or two. What do you think?
