I have to agree with aart since it looks like you have the roost directly above the nest boxes, you need to make sure they don't foul those nest boxes. A nice landing bar just below the boxes and out a bit (8" as mentioned by others is good) for the hens to land on before going into the box. Other than those things, I like the setup and the idea of using milk crates for next boxes.
