I have been reading threads and in one it was mentioned that a cement floor in the coop is difficult to keep clean. I am planning on using straw or wood shavings for at least the first year (due to cost) and, maybe switching to sand in the future. I will also have poop boards under my roosts. My coop will be a ground level, walk in 4X8 coop. Does anyone have experience with cement floors and some advice? I know cement is porous and may have to seal it in the future also. (I'll be looking at Habitat for Humanity for things like this).
