I lined my runs with 1/2" HC, 2' high.I like coarse wood chips as well. The hens love them. Only problem I have is they kick about 3 wheel barrows through the mesh every month. I've learned to pile it in the center and let them work it to the outside when I put it back. Doesn't take them long...![]()
Actually did that to keep tiny chicks from escaping, holding the wood chips was a bonus.
