My chicks will be going out to their coop when it arrives in 4 days they will be 4 weeks old. I am using pine shavings right now but I would like the best options for the chicks and myself. My coop is going 6x10ft minus a 3ft tack room. Its basically a little building being made my run will be 6x10 ft. the whole thing on skids that I will move through out the yard/prairie. So my main question is what to use on the floor of the inside of the coop?
