Just wanted to come back to add what I couldn't before. My job gets in the way sometimes
If you create a manure pile, remember that it will "grow forever" unless you know for sure you can find someone to come and clean it down once or twice a year.
Or if you have enough property and live in an unincorporated (rural) area, you can spread the manure and shavings.
I have four horses that come in every night, so I clean the manure every morning.
