i have hauled truck loads of chicken litter to a plantation in south Georgia it came wright out of the chicken houses they said it loses nitrogen if left out in the weather they spread either 1 or 2 ton per acre on the corn fields and plow it in , as any fertilizer to much is bad, i have no idea on how much quail litter to use
good luck tony
how about making it into a compost pile and letting it rot down? You'd know from the smell (earthy not pooey or ammonia) if it was ready to use. You need to cover it with a tarp preferably and keep it moist but not soggy. Should end up black, crumbly and full of worms. With regards to losing nitrogen that's not a bad thing as fresh bird poop has so much raw nitrogen in the form of ammonia in it that it scorches plants. It's better to let the nitrogen be broken down into a safe form by microorganisms.
