Minecraft wiki entry for Villager, associated text: To share, a villager finds its first inventory stack with at least 4 bread, carrots, potatoes, or beetroot or with at least 6 wheat, and then throws half the stack (rounded down) in the direction of the target villager. When wheat is shared, it is first crafted to bread, which may result in 1 or 2 less than half the stack being shared.
