I have an 8X20 coup. I sections off half of it when I got my 26 baby chicks so they would stay clustered up and noone get lost. They are now 4wks old so I removed the partition. I put sand in the new section and planned to put sand in the old section as well, however the pine shavings still look pretty good and don't smell so I was thinking about leaving the shavings and mixing it with sand. Has anyone else done this? Any suggestions?
