There are a multitude of different metal fence options that you can obtain so that you can create a contained space for your piggies to have grass time or play time. This particular one has sections that can be pushed into the grass so that it won’t move. You will also need to put shade cloth over the top to ensure that piggies are protected from sun and also from predators like birds of prey. If you are in an area where there are cats or other large predators, then this play time housing needs to be supervised the entire time! Do not leave them un-attended or here in hot weather conditions.
