Thanks for all the great feedback so far!
The cage is just for roosting and nesting, they would have access to a secured chicken run (the space under the long wood pieces and 15 sq feet of the ground covered with pebbles in front of the cage all day long (I won't be closing the cage door at all). To boot, they will have access to the whole backyard on the weekends. The cage would have Zero sun exposure, actually not even the run really has exposure, which maybe a problem. The ramp is just an quick example (it is wood painted black).
Instead of a standard roof I was thinking about the triangular lean-to roof to maximize storage space/roosting space/space for me to get into the pen.
thanks!!!

ps. good note on the metal of the cage as a heat issue.
pss. predators: raccoon, possums, other cats, our cat Sid is mostly harmless, very friendly with all animals other than small birds.
psss. Do I need more insulation than what is shown for chickens in Los Angeles? Some mentioned puting some wood siding around the cage instead of just burlap. Maybe burlap in the summer, plywood siding in the winter? Is that more for their "sense of security" or do they need it for insulation against the cold?
