Baby villagers can now farm crops and trade as of the 1.13 update aquatic.
- Create the crop farm designed by m0rsk: https://www.youtube.com/watch?v=dbz4xfzwMIc (note that due to another unrelated bug, the waterless version of the drop shaft must be created, as the water will update the crop land next to the villager)
- Spawn in a baby villager
- Kill the villager if it is not a farmer (I could not get any villager type other than the farmer to harvest crops; I'm not sure if this is intentional or not, but in 1.12, any brown coat could farm crops)
- Watch the baby villager harvest crops. It can be clearly observed that the baby villager now has an inventory, something that didn't occur in 1.12.
I spent a lot of time trying to debug my crop farms in 1.13, only to discover these nuances. I have noticed that this doesn't always occur; I haven't been able to fully understand what the issue is. I've attached an image of a baby villager farming below.
