The children's farm? That is an interesting place to put Chacoan peccaries. Was this a former domestic pig enclosure, perhaps for a rare breed? I will say however, to be fair Phoenix Zoo does keep taxa like the Visayan warty pig, Calamian deer, and Central American red brocket on their Children's Trail.
@UngulateNerd92 Yes, it's a pretty weird choice. I think that even if this enclosure is part of the children's farm, it is considered as an enclosure for a non-domesticated animal. Before Chacoan peccaries, red river hogs lived in this enclosure.
