So far, all my wood chips have gone to the garden, and probably will for a while yet. I put lots of raked up leaves in the run this fall. For the coop, I've bought three bales of pine shavings from TSC, and 1 bale of hemp, which was $33, so not cheap. I will probably get another bale of hemp. I like the mix. The pine shavings are springier, which I think helps with the chickens getting a soft landing when they jump down from the roost.
