I got rid of all my silkie chickens last month and now their coop/run is empty. I'm thinking I'll probably get more bantams and house them in this coop/run next year and am wondering what the best way to "cleanse" the run is so I won't have a problem bringing new birds into this environment. The run has sand and is about 4 inches deep. When the silkies were on it, I would use my hoe/rake to fluff up the sand about once a month or so and the rain seemed to keep it fresh looking/smelling. I'm thinking I should probably be "treating" the sand now before winter/snow sets in so it'll be all set next spring. Would DE or garden safe lime be the best choice OR does someone have another alternative/suggestion?
