I wasn't sure where this topic belonged, thinking maybe since DE is used quite a bit around the coop and such that it would fit in this section. But I went to my local feed store for a few things today, and a bag of DE caught my eye. I have never used it before, but after reading so much about it on the forums here, I thought I would give it a try. It cost me $32.95 for a 4 pound bag!! I guess I had better use it sparingly. What all is DE good for? I was planning on using it to dust the floor of the coop, nest boxes and dust bathing areas. It is also pet grade and can be put in their food. Anyway, what all are you paying for this stuff? You would think it was as valuable as gold!!
