I never said anything about concrete expanding and contracting. I'm sure it does. But when I say the rubberized roof coat is the best, I'm not just talking about a theory of mine. I use it in my coop. Like I said, it has been in there over 3yrs, through all kinds of weather and temp extremes. From lows of 10F(And sometimes below that) to over 100F. It has gotten wet from rain blowing in, and spilled water founts. When I clean out the coop, the roofcoat looks the same as the day I put it in there. There is NO cracking or splitting or separating from the floor. I don't care how it performs on a roof. Maybe it does crack or fail in some way. Maybe it really can't stand up to being exposed directly to sun. Maybe it was improperly applied to begin with. But on a coop floor, under a layer or shavings or sand (Yes, I have both) it just plain works. It isn't a cheap floor treatment like vinyl or linoleum, but it beats the cost, and it's much easier to use than epoxy, no mixing needed.

You've convinced me! I have a painted plywood floor on the coop I inherited with my property when I bought it. I was going to just whitewash it and add sand, but I am concerned about the wood holding up over time - especially when it's time for a good scrub clean. Do you have any problems with your chickens scratching any loose? Did you go up the sides at all? My little bits are only two weeks old so I have a bit more time to get the coop finished - but not too much.
Thanks in advance for your thoughts. I'm very new to this - feel like I've done more research on chicken keeping than I did on my thesis.
