I have always had good luck with the shavings. I have been using them for 18 years, and I have never had cocci. I do stir it daily, and manage the bedding keeping it dry. The bedding gets changed every two weeks. I will also freshen it up a bit if I feel that I am going too far. I have 78 four week old chicks on bedding now. I will be putting 72 plus or minus within a week. I like the bedding because it insulates the floor, hatching this early(which I usually do not). I also use the bedding in the compost piles. I do not use medicated feed either. My luck, I will see cocci this year, but so far so good. I rarely lose any chicks, less a couple that you can't do anything about anyways. I think the trick with bedding is staying on top of it, keep it dry, and when the bedding can't keep up with the load, move the birds up.
