I have just completed a new coop for my girls with plans to add to the flock. In researching bedding for the coop, I had planned on sand but am not completely sold, I found an article on Pine Bedding being toxic. See link below. I am open to suggestions as I am looking for the safest for the girls as well as the easiest to maintain (As if anything is really easy).
