Welcome, BYC is full of information and experience. Paint is drying on this latest project. Outside access for nesting boxes so I do not have to open the big doors. The idea is when it is cold and blowing I do not have to let the heat out. When I work part time I do not have to worry about opening the big doors and having chickens escape into the yard when I am about to leave for the day. I might add insulation of some kind because eggs do freeze in my part of Ohio in the winter if kept in the nesting box all day.
