Right now it's Timothy hey and pine and dirt in one side. They love that section. When we pour water out every night they like to float in mud. When we get the area done it will have a drain leading to front gate in the other side is a garden. That will eventually get netted off so they go up front. We our going to build a large coop house in back yard for them and split it off for chicken and ducks. My dogs don't need a lot of space. Just enough to go to bathroom. There inside dogs.
