Yup. Well, the top one is hay storage, half of the rest seem to be nest/roost. All the coops I saw growing up were done like that, with shelves and sometimes shelves built into cubbies. My girls do prefer the spot closest to the corner for nesting. I also messed up on the height... I started out going 12" high and then started second-guessing myself; I wanted large breeds and thought I'd best switch to 15" high.
its always so interesting to see the way coops are built differently in different parts of the world. Never have seen shelves like that in your coop. Seems very practical!
