Was not a big deal at all. I was able to remove all 3-5 inches of pine shavings/saw dust in a few minutes with the garden hoe. After setting in that little coop all winter with 6 hens, I was very surprised how good of shape the shavings were. They could have easily lasted another three months. Dry and dusty are the best words for it. The untreated OSB floor still looked good as new. Shavings were so clean, Ill have to soak them in fish emultion to get them to decompose before spring planting. I put in some new shavings of dug-fir from my neighbors planer. Pine fresh sent! So easy too and I owe it BYC for the education. Thank you!
