Last year was my first year with chickens. I quickly learned I had the coop in the wrong location and it soon became a stinky wet mess. The smell was awful, rotting chicken crap, water, mud and shavings . The coop has been moved to the correct high and dry location and has a well covered run that stays dry in all but the heaviest rains. The ground where the coop was still smells bad. What can I do/put on the ground to kill the smell? The old area is still fenced in so I'm not concerned with the chickens or anything else being directly exposed to the ground.
