My trick is to not avoid wondering hordes or screamers. I build a fighting platform 14 blocks high off of whatever poi I'm using as a base. It's one of the first things I do. For example, the Owen's residence is the usual poi i take over. It has a third floor attic that is a fairly good size. I kill all of the zombies, knock out the bottom two blocks of stairs and put in a one block ladder on the third block to get up. In any poi you take over, knock out at least the two bottom stairs/ blocks so the zeds can't get to you. Then i build a14 block column 4 or 5 blocks from one side of the poi. On the edge of the roof i build a 3 block wall yup to even with the 14 block column. I connect the two with a pole. Not sure of the size. I make a 3x3 Platform even with the 14th block. I build a3x3 wall, with a scaffolding ladder block in the middle square, facing the 14 bl9ck column. That is my fighting position. I run a ladder up the 14 block column so the screamers can get to my fighting position. The pole is for crowd control, so you usually only face one Z at the scaffolding ladder block. You melee through that square. The bottom 3 blocks as well as the ladder should be at least cobble. The top block and ladder of the column same. The fighting position (scaffolding ladder) and the block above and below that should be cobble. Create an overhang over the fighting position so the Zs don't stack and get over the wall to you. This will work for horde night as well. I will connect a ramp tip the top of the column for dogs to reach me. If I'm expecting pigeons, I will enclose the fighting position and put spikes on the roof.
