So I've read a TON of great things about using river sand in your chicken coop. They all sound like great reasons to me but I've never had chickens before so I don't really know what's best and in what order. We were thinking of doing sand in the summer and hay in the winter. Live in Wisconsin so the winter temps get pretty cold. I would like to hear from you all about who uses sand or why you don't like it. Please and thank you!!
