I have read so many conflicting articles on the use of sand in the coop/run for chickens. Some say it is great (as long as it isn't play sand) and others say it carries Ecoli, or is bad to use. I am setting up a coop/run area with a bigger run area attached to it. The largest run will have deep litter in it. I'm looking for the best ground cover for the smaller (5'x10') run area - it will be covered. Sand sounds good, especially since it can be easily cleaned, but I want what is best for the chickens and our health. So, what is the real low down on sand?
