I cover the wood floor of the hen house with Natures Pine bedding pellets. I buy them for the horse stalls but will fluff up a bucket full with water and spread it on the floor of hen house using more right under the roosts. I clean it about every two weeks. The only place that is messy is the floor under the roosts. In the nest box area I use grass hay. The hens really like to get the seed heads it contains and then they make nice soft nests for egg laying. I change that about once a month to freshen it. I am on acerage so getting rid of the used bedding is not an issue as I have a compost pile.
