My tractor sits in the grass, and my "three girls" fly up to the roost near the top at night. I move it to a new location twice a week mostly because of the large amount of poops and their smell. (The girls are set out to pasture for about 3 hours each afternoon.) How do I use hydrated lime or food grade DE to cut down on the smell if I'm not using shavings, etc. in the grass? (I only have shavings in the roost/nest box area.) Every post I've read talks about mixing the lime or DE with shavings of some sort. Could I just sprinkle lime or DE directly on the grass? Will it kill the grass? Should I sprinkle the new area prior to moving the tractor or sprinkle it once the poops have built up before I move it again? A little confused about the process, and I'm a newbie. Thanks for your patience! I'm sure you all have walked newbies through this same thing a bunch of times!
