not sure if this is the right place to post this...i know i saw it somewhere on this site but can't find it. my local feed store does not sell food grade. i'm planning on using the deep litter method (with DE), however, i just read today that the deep litter method should not be used in small yards (near neighbors) due to the smell and that i should just clean the coop out every week. i guess this has become two questions now - thanks in advance for your help!
