Pigs naturally live and spend their time in groups. They express friendships with each other through vocalizations and body language. Like human children, piglets are particularly fond of play and chase one another, play-fight, tumble down hills, and generally engage in a wide variety of enjoyable activities. Pigs are very active, traveling up to 30 miles a day at a quick pace.also spend much of their day grazing and rooting. Pigs raised on factory farms are denied all of these behaviors.
