My coop/run combo is underneath my prized Red Oak trees. I have sand in the run and rake what I can, but occasionally rain washes the poo away. I also have a small cocnrete slab where poo accumulates. I scrape it up, but again, when I rinse with a hose, some poo residue is left and it gets washed away. Will adding pelletized lime help with this? I don't want to make the soil more alkaline and I know Oaks like a slightly acidic soil, so I'm looking more to neutralize the alkalinity of the poo as well as keep the smells at a minimum.
