Good start on the coop! I like that you made it tall enough for a human to stand up in, that makes cleaning a lot easier. Don't forget to give it plenty of ventilation and to use hardware cloth (not chicken wire) on any/all openings to protect the flock from predators.
Hardware cloth of 19g 1/2 inch should be over run and all openings to make predator proof. It has to be at least that small and that strong. Most recommended item.
