I'm new to the forum, but have been lurking for some time now. Has anyone tried using linseed oil, used peanut oil (from the deep fat turkey frier - eeek), or similar cooking oils painted on the coop floor? I knew a guy years ago that 'painted' his used motor oil on his coop floors and ramps to seal them from moisture. It didn't seem to have any ill effects on the fowl, but personally I wouldn't risk it. We used linseed oil to oil forms for concrete work, and I have some left over. I thought it might put a good seal on a new plywood floor. Is this a good idea or not?
