I've created a model farm, but my animals keep wandering all around the place, and I can't keep track of them! I've set the config to ambience mode so that they don't need to eat or drink, but I can't tie the animals to a lead all the time. I could definitely do something like this with custom NPCs, but I would like a better solution. I know it goes against the core purpose of the mod, but I would like it for the sake of creative mode farms. Thanks!

Use... fences?
