Minecraft wiki entry for Iron_Golem, associated text: In Bedrock Edition, an iron golem can spawn naturally when a village first generates in the world. Iron golems also spawn in villages having at least 20 beds and 10 villagers. The golem attempts to spawn in a 16×12×16 volume around the village center defined by a bed or a bell. For a village to spawn iron golems, 75% of the villagers in the village must have worked in the past day, 100% of the villagers must be linked to a bed, and a player must be within 64-128 blocks horizontal and 44-108 blocks vertical distance from the village center, depending on simulation distance.
