Villager Breeding and Iron Farms: The Mechanics That Make Them Work
Villager breeding requires beds with clear space above them, sufficient food in villager inventories, and villagers detecting unclaimed beds, with the food requirement being the most commonly missed. Iron farms work by triggering the village golem spawn mechanic, which needs villagers who have slept and detected a threat, typically a zombie kept nearby but separated. Both systems fail silently rather than reporting what is missing.
