If you already have the chain link, then yes, add it! But secure very good to the ground with long stakes, if you can get 3/8" or 1/2" re-bar used for concrete work ... You can make stakes out of that ... Cut a 15" long piece, and bend a "U" at one end, slide it through the fence and hammer into the ground ... You may find you ground softens up a lot when it is wet ... So a little soak before pounding may help ...
Some people put a "skirt" on top the ground if the want dig protection, fencing layng on top of the ground, held down with rocks or stakes ...
