I have been looking for DE locally without luck. I have seen many web sites that have DE, but I am too cheep to pay the price of the shipping, which can be more than the cost of the DE. Yesterday I went into a local farm and garden store and found a product called Sweet PDZ. According to the label it will dry up moisture and keep the ammonia down in areas where livestock live. It even says that it can even be used for chickens. I purchased a 10 pound bag of Sweet PDZ for $5.39. I only have 4 chickens so I shouldn't need more than that. Iwould be interested in hearing from anyone who has used this product.
