I have my own makeshift deep litter method in my coop which includes raking up grass clippings every few weeks and throwing a layer in. I try to put some in, then next time I add leaves, then next time some straw or pine shavings. Just not the same thing over and over. I add a few inches every couple weeks and do this for 6 months. It makes a nice compost that I then spread on my garden twice a year. Never had the grass clippings get slimey or stink.
