This is the soil right outside my chickens run. Our soil is VERY sandy as you can see. I have tried putting sand in my chickens pen and I did not like it. I spent hours out there scooping poop out of it and in just a weeks time the smell was horrible. Standing up I could even smell it. Anyway this is the soil just outside the pen like I was saying. Then this is the soil inside the chickens run where I have been doing deep litter now for I don't know how many years. I have NEVER seen puddles of water in their run and I am in the hot humid south Ms. area. This hen was being a little nosey. lol As you can see it needs replenishing again. Hopefully going to do that tomorrow. I try to keep it in there and it's breaking down VERY well now since I don't use any sort of chemicals and I don't use that powdered stuff that people use and say is safe. I don't use the stuff. Another pic of the soil outside the pen. and one inside the pen. Just LOVE this method and another great thing about it is I can go in there and scoop out soil for my garden just like a compost and they're not having to wade in their own poop it just disappears in the deep litter. Can't say enough about this method!!
