Great looking coop!! One idea- if you have laying hens you might want to consider finding a way of covering the windows if your going to have your roost by the window. Chickens need rest to lay good. I don't know your surroundings but if there is constant movement going by the window, pets or night time predators, then hens will be on constant alert which causes stress. It will most likely effect egg production. Something simple like a shade would help. Just a idea.
