I'm in the process of getting the container ready for the new arrivals. The first 3 or 4 days I've read to have a slip free flooring. At first I put Pine Shavings down...that's OK but I seem to never be satisfied so I replaced the Pine Shavings with a Easy Shelf Liner ...better grips. In testing my lamp I was worried perhaps the heat would make the shelf liner give off fumes. The heat lamp is 18" above the flooring material. I really need to see if any here have used shelf liner? When I am able I'm going to check temp under lamp (can never find a thermometer when I need it). Heard paper towels for the first few days were OK. I've raised chicks before and I never gave a second thought to flooring. I used newspapers with success may revert to that. What do you use? Thanks in advance.
