Commercially available chicken hutch.  Visually it looks great but it offers very limited space for the chickens to move about.   It does offer easy access the nest box as the roof over it doubles as a lid that can be lifted up.  Image courtesy of the internet.

A flat roofed commercially available chicken hutch.   Notice that there is a small gap under on section of the frame due to the ground being uneven.  This offers a tempting weak spot for foxes to dig under.  This can be easily prevented by tacking chicken wire to the base,  but then the chickens won't be able to scratch the ground.   Image courtesy of the internet.
