how do you breed villagers minecraft?

once it's running, give one of them a farmer job next to a crop farm. farmers harvest and toss spare food to the others, so they stay willing without you feeding them. wall it in though, or the babies wander off and zombies get them at night. and the villagers have to be able to actually walk to the beds. a bed they can't path to doesn't count, so if you've boxed them into a tiny cell with the beds on the other side of a wall, that's why the hearts never turn into a baby.

Two things have to be true at once: there are more free beds than villagers nearby, and the villagers are "willing". Willing just means they're carrying enough food, which is 3 bread or 12 carrots, potatoes or beetroots each. Throw the food on the floor next to them and they pick it up themselves. The bit that catches everyone out is the beds. A bed only counts if there's free space above it, and a baby villager will claim one as soon as it's born, so if you want the population to keep growing you need to keep adding beds. If you see hearts but no baby, it's almost always the bed count.
