I was thinking about how the urine of the chickens soak into the wood flooring making it hard to clean and get rid of the smell. So with rabbit hutches, goat and horse stalls. The idea of vinyl flooring popped into my mind. It would make cleaning simple. Even lining the walls for really messy animals. The only thing is you would need to put enough hay or sawdust down so the animals wouldn't slip. I did a google and found out I'm not the first to think of it for chicken coops, but I don't know if anyones done it for other animal housing.
