How do we allow our 4 kit rabbits and 4 adult rabbits to run free in a space in the yard. How do you predator proof it. Deer netting on top.. Do you dig 3 feet or more down and put some kind of heavy netting. Not chicken wire fencing because it's to them and can be eaten through.maybe concrete on top of it.or wood or metal. Space around area. Wood bricks netting or fencing.something to block holes. A warm shed I enclosed for shelter. Anything else.
