Alright so the only available spot I can legally build my coop and run due to municipal codes for my location is completely concrete. I cannot free-range my chickens at all because of the animal laws in our area concerning chickens and a heavy predator bird population in the area. That doesn't matter anyway because my entire backyard aside from a small planting box is concrete anyway. I am planning on building an elevated coop with wood floors covered in linoleum and then topped with pine shavings. My question is for the run: even with roosts, will living their lives on concrete be bad for my chickens feet? Do I need to put anything down in the run (keeping in mind that at night it gets very windy in my area, so sand/pine shavings/etc. will be blown away)? I am planning on sealing the concrete, building an outdoor dropping box with roosts, and setting up an artificial dust bath bathtub. Is this enough?
