For those of you living in Florida, the Gulf Coast, Seattle, or any other areas that receive a lot of rain, what kind of floor do you find to be the best in your coops? I'm now living along the Texas Gulf Coast, and we get a surprising amount of rain in the spring/summer. I'm planning on starting a small, urban backyard flock in a month or two and I don't know what I want to build. I know I can't use shavings, or dirt because it would be a moldy, muddy mess. I've thought about doing a layered floor with limestone/sand/pea-gravel but wonder how hard that would be to clean. And I know that I definitely do not want to do the plywood floor with shavings that I've done in the past, because they are labor intensive. Any suggestions that I may not have thought about yet?
