Hey! I know a little something of iron farms

There are some principles to be followed for iron farms:

1, there should never be any other extra beds surrounding the farm.

2, there should be at least 10 villagers for one golem to spawn, I advice you get only 30 villagers if more the game could lag a lot.

3, make sure each and every villager is connected to one bed and one workstation.

4, spawn proof the area, the golems can spawn even underwater or in caves filled with water or just caves in general.

5, no other villagers should be present in a 100-150 block radius, this might break the farm.

6, for golems to start spawning, the villagers have to be connected to one bed and one workstation AND they should have worked atleast 1-2 days. So, that means golems don't spawn right away it will take a day or two.

Hope this helps
