Still working on the human door and the nesting box door. Max capacity of six hens. Questions: * Hows the roost hight and location? I wanted it close to the human access point so it's easy to clean. * I'm thinking DLM so I made it about 6" deep, are the little step ups okay for the nesting box and exit? * Where should I put windows/vents? * I live in the north east so I should add insulation to the walls? Thanks.
