I have a 10x14 roofed and enclosed run with a 5x4 raised coop for my 5 chickens. The coop floor is covered with stray, maybe 3-4 inches and i clean the poop daily. Is this ok? My run was grass until I added the chickens until i added the chickens. Now it is dirt and stray they have dragged down from the coop. Does the run need some time of ground cover? Can I rake it up occasionally and just leave it hard dirt? Thanks for your help. I sure do enjoy my 5 girls. It was 6 for the first 3 days but I hadn't buttoned the run tight enough and a critter got one.
