I have done some reading here and think I have the answer, but a few opinions never hurt... Our run is uncovered and is dirt (now that the rains have started, mud) and I spread some straw down over the extra muddy parts and it has turned to muck. I give them kitchen scraps daily and just throw them on the ground. wondering if I should be concerned about them scratching around in their poop/mud (mold) mess? It sounds like we should invest in sand, lots and lots of sand. The problem there is that our coop sits on the top of a bit of a slope. Wonder if the girls would just dig and shift the sand down to the lowest point? Also, they do dig some pretty impressive holes, would they do the same in sand and just get to the dirt under the sand? Lastly, they do have dry space under their raised coop, 4x6 foot space for 5 birds. Do we NEED to give them more covered space than this? Thanks for your thoughts.
