I use this controller for my movable hoop coop - zarbeba
It does not require a ground. However, you will have to use an extension cord. It has been protecting my chickens for about two months. The only problem with it is that if any blades of grass touch the wire it does not work. Mine is mounted too low in some places. But for $30 it is worth a try.
