The nesting box attaches to the coop using two thumbscrews. It sits on a ledge that positions the nesting box against the coop.

The white frame in the foregound will be the door providing access to the portable fenced-in area. It will be painted green, like the coop's exterior. See the last photo below for a view of the door's location.

The feed trough looks a lot like a piece of rain gutter.

Look carefully for the rope and pulley that operates the ramp to be closed at night, protecting the ladies from critters.
