Vinegar is sometimes used to kill bacteria on surfaces, due to it's acidity. They've done studies in labs on this. You can google vinegar and antibacterial. It also kills mold.
For deep litter, I only start with enough shavings to thoroughly cover the floor. For me, starting with a thicker layer just means more stirring. I top dress lightly with clean shavings as needed, in the areas of the coop that need it.
I guess I'm doing a lasagna method, where the clean litter and the chicken's "input" are gradually layered in the coop. Rather than having a really thick layer of clean litter on the bottom that has to be stirred up to the top, to deal with all the chicken poop on the surface. That takes a lot of stirring, right from the beginning. I prefer to just regularly scatter a little litter where I need it. I'd rather have the cleanest layer of litter on top, where the chickens are walking, too.
When I first started doing deep litter, I did start with a thick layer of shavings and do a lot of stirring. This way just seemed more logical and like less work, so I started doing it this way. Either way works. You just have to have enough shavings combined with the chicken poop or you'll start to smell ammonia.
