Hi all, I'm looking at this as a coop and run for 6 hens. Overall, it would be 8x12 with the coop portion being 8x4 and the run 8x8. I believe both are more then enough for the size of my flock. My question is concerning the floor of the run. It would come with a hard floor whether that turns out to be wood or trex or something else. I can put dirt, grass clippings, etc in the run area - would that be ok? Thanks for the input. Appreciate any and all help.
