How to build a chicken coop
The nesting boxes and storage area plans
The front and internal partitions in the nesting boxes/storage area combination are of 1" x 12" (300mm x 25mm) boards. The sides, the bottom, the nesting boxes' lid and storage area door are 3/4" (18mm plywood). The storage area door is not shown in this plan.
There is a gap or cavity between the internal partitions separating the nesting boxes from the storage area. This allows for two separate exterior lids: one above the nesting boxes and one above the storage area. Make the lids larger than the area they are to cover, so they overhang at the sides and at the bottom. They can then be hinged to the 1" x 4" (100mm x 25mm) piece of wood that runs along the top of the unit.
