Do iron farms work in skyblocks?

I just want to know before I use all the iron for an anvil (for a name tag). I got a zombie right up to the villagers and they weren't bothered at all. Does the zombie need to hurt the villager first or do they just not get scared in skyblocks?

@Piston427 might be too late, but in order to make an iron farm you have to rely on the natural spawning mechanics of Iron Golems in pre-1.14. Which requires doors and I believe 12 villagers. Just look up 1.8 Iron Farm and you should find it.
