Hi! We have our small flock (four hens, one roo) in Mississippi. They have a medium-sized run area outside their pen. Lately there's been a lot of rain, and our soil is clay, so it's starting to really reek of ammonia. I've read on here that pelletized lime can help IN the coop, but the coop is fine. Will that work just as well outdoors? Is there something better we could use? I appreciate your responses!
