We finished our coop and have moved everyone in, but the floor is wood (it's raised off the ground). I'm worried about the cleanliness and smell long term. Is there something we could put down that would be easy to clean that would be waterproof so nothing can penetrate it? Right now we just have a tarp lining the bottom and part ways up the walls (it was bigger than the floor). We don't think this will be a good permanent solution for us though. Any suggestions/tips/advice are welcomed and appreciated! Thanks!
