Minecraft wiki entry for Zombified_piglin_farming, associated text: The simplest zombified piglin farm is to dig a 3x3x1 trench and make a layer of dirt leaving a 1 block space. Shoot zombified piglins and swipe at them with a sword on their legs after they jumped into the trench. Turn on subtitles, so you can hear when you can come out. To get maximum spawn rates, slab off the blocks in a 128 block diameter. It is done! You can also use magma blocks which only zombified piglin can spawn on(if you are on 1.16)
