Here is my coop I designed for a winter project and ended up building it right away in December, it will be used for breeding silkies. The coop measures 3'x3', the run measures 3'x10' and is 4' tall from the ground to the peak. It is built with 5/8 thick T1-11 plywood and 25 year architectural shingles. I did a lot of figuring to only use a total of two 4x8 sheets of the T1-11 plywood for the entire coop (all 4 walls, floor, roof sheeting and nest box walls, lid and floor) The coop has 2 coats of paint on it and the run is stained and coated in Minwax outdoor urethane. The bottom of the run is made out of cedar where it comes in contact with the soil to prevent rotting and the rest is pine. The run is covered with 1/2" hardware cloth. It has a hinged external nest box to collect eggs. Half the roof is also hinged to allow access to water, feed and clean the coop. The rear window hinges and the opening is covered in hardware cloth. There is a door at the end of the run to free range the birds and for access the run. The pop door is operated by a pull cable outside of the coop at the peak.
