I am building a new coop this fall and I was going to use a plywood floor covered with pond liner. However, I'm not sure if I should cover the liner with tile. If it's not too expensive. But the most important question I have is. Should I leave it bare or put shavings down too. I live in Florida so I'm not too worried about the cold. I want it to be simple and I'm looking for the easiest way to keep it clean. Thanks for any suggestion or experience you may have.
