Just follow the marks on map and youll find them all, nothing hard :)

(marks are on exact spots where prey is)

Different types of chests:
-
-
you can also find wine cellar at Cotton Ball, behind the bar

what i manage to spot is, that every chest have a small swarm of fireflies
fireflies realy help you finding thes chests at night, highly recommend you to at least use them to find all the chests at city


also loot is random! so keep that in mind that every time you start a new game you will get diferent items from "chests" and "wine cellar"
