I am very lost with this whole project. Growing up around farms didn't help the logistics.
But keeping the monsters down helps - I have only ~4. One burrows like a mole, and giant spiders and land-octopuses could just clambor over any wall.
The inner walls around the baileys are only there for basilisks. I figure small huts might be placed around the farmland, so people can run inside. No way anyone's out-running a giant arachnid. They must move at least as fast as a horse.
