My Nephew gave us 3 of the Stromberg starplate kits to build a Coop, woodshed and Gazebo. (He works at a lumber mill and was able to get the 2x4's for the framing at an awesome price. ) The floor space will be. approx 140 square feet for 12 chickens, height may be 13 feet. We plan on having 2 levels to roost, a place for nest boxes even though they currently don't use boxes and lay eggs in a corner. The current housing will be modified and used for the run, it is currently 15x8 wire enclosed A frame. http://www.strombergschickens.com/starplate_building_system It will be built on the ground, partially below surface about 6" and secured down with rebar driven into ground as we get high winds here, with cement around exterior posts. (building on frozen ground will be interesting) I plan on making a wind break or a section of plywood 1/2 wall to prevent wind from getting into coop when human door is used, may be inside or more then likely exterior. In the walls will be making cutouts for plexiglass windows, that can be covered or filmed to prevent heat in summer, covered with wire to prevent critters from entering. Vents will be small hooded vents to prevent wind entering, thinking of 4. Thinking of adding a smallish platform inside to increase areas they can go, and to raise water and food off floor to make it easier for me to feed & water. (back issues) Exterior walls will be plywood, still deciding on thickness, and if we are going to cover with siding. We have lumber and other materials that can also be used from other projects that was left over or scraps. My nephew was suggesting making a small entry way on exterior where the feed could be stored. I like the idea but because of bears I'd prefer keeping non food items out there. We are still tossing ideas on the build around but plan on doing the project during school winter break to give his boys a chance to learn a bit about building AND keep them busy. Any ideas or thoughts of the build would be welcome. Even if you think this is too small, large for the number of birds, things that should be added any input appreciated. .
