This is as good a place as any to discuss chicken poop! Litter management is mostly about containing and controlling the poop.
Chicken droppings are acidic and high in nitrogen as well. Remember, chickens don't urinate, the white stuff is uric acids. So, manure from birds and reptiles is much different than that from mammals. The lime helps to bind the nitrogen as well as raise the pH (lower the acidity). I use pulverized lime stone because it has a sandy texture and is NOT fast acting. A fast acting lime can harm the birds feet.
