My 2 star wolves and boars are enclosed in a large area (twas originally a dilapidated, abandoned village) adjacent to my castle. It is surrounded by a 3-4 metre earthen wall, which has a 1 metre trench on its outer base. The area is blanketed with work bench & ward anti-spawn coverage and it has never suffered from invasion incursion event enemies. The wards are buried just outside both its southern & northern gates, because wards not only create anti-spawn coverage, they also increase the strength of player made structures (like large darkwood gates). Due to the fact that I rarely ever use the gates, they are blocked by the largest stone wall pieces.

I repaired and repurposed 3 of the five buildings in the village, and demolished 2, using their base for garden plots because they left me with 2 perfectly level areas to use for garden plots. This allowed me to minimize the amount of hoe levelling, which in my experience is one of the main culprits of lag.
