I have heard about 50/50 positive and negative aspects of sand bedding in the chicken coop. I am dying to use it for its "cleanliness" and convenience. However, I have heard from some sources that it can harbor ecoli and coccidiosis. I am all about convenience and having a sanitary coop, but also want the best for my girls. Bottom line: is sand bedding good or bad? What type of sand should be used? What are the cons of sand in the coop?
