I keepp every thing outside, keeps cleaner inside as birds hang out more outside, also keeps mice and rodents down as there is no food fo them inside, I put the food in trash cans at night wich also discourages predators from coming in looking for food, even though my coop and run are fairly safe, 5ft 2x4fencing covered with heavey mesh, extra chicken wire around bottom and an electric wire 12" off the ground
