OMG, I cannot believe the difference the wood chips or shaving make in my chicken houses. I used straw a lot in the past thinking it is good compost material. I just rake the chips out and put in my compost if I start to smell any odor at all. Or sometimes I add a little more chips if I don’t have the time to clean the house out.
I went to my daughter’s house and her chicken houses were loaded down with the wood chips, six or eight inches. She said you just take a pitch fork and flip it over as you see poop on top.
There is literally no smell even during the hot summer months. You will love it.
