We needed a larger coop. We have a 4x8 tractor with penthouse that serves as a soil-builder for our raised beds. Also we have a mini-tractor/brooder that sits in the garage. We need the garage space.
So the plan was to build a coop that will serve two purposes. 1- house my RIRs, and provide a small section to brood and grow off future chicks. Each will have it's own pop door and run. The basic floor plan will be 8'x8' with a single sloping roof. All lumber is to have a minimal amount of cutting. All ply or OSB sheets are to be installed with no cutting, except the incline of the roof angle.
Provided here will be the materials list, Costs, and cut sizes as well as assembly methods. Hold on - here we go!
| 2x6x8 PT
| 23/32 x 4' x 8' OSB T&G Flooring
| Liquid Nails
| #12 x 3 1/4 Galvanized Nails 5 lbs
| 2x4x8 studs
| 1/2" x 4' x 8' sheathing or plywood
Tools..... Skil Saw, Tapemeasure, Pencil, 16oz Hammer, Framing square, chalkline and level. These are the minimum. For all my cross cuts on framing lumber I use a compound miter saw. But a steady hand with a Skil Saw will do just as good.
1. Take the nine 2x6x8' boards and cut 7 of them to 93" exactly. Take the remaining 2 and leave them at full length. However, check the length and make sure they are not too long- if so, trim them to exactly 96". Using your tape measure, mark lines at 16, 32, 48, 64, and 80 inches. Do this on both 96" boards. Then nail or screw them together in this manner.
Once you have nailed it all together, it should look like the picture below. Measure from one corner to the opposite corner, and then cross corners and measure the other way. If your floor is square both measurements should be the same. It not then bump the longer corner with your hammer until the cross measurements are the same. Now you are ready to install the runners ( skids). These are not needed if you do not wish to ever move your coop. If you are like me and desire to rearrange things from time to time, then you can install these and you will have a portable coop that you can hook to with your truck or tractor.
2. Now take the two pressure treated 2x6x8s and cut a 45 degree angle cut on both ends of all four. Once those are cut, then lay a snake-like bead of Liquid Nails along the broad side of two of them. Get your garden hose and spray a little water on the other two boards. ( Water activates Liquid Nails which is a polyurethane glue ) Then sandwich and nail together a unglued board to a glued one and you will end up with two 4x6 runners. Measure in from the 96" 2x6s on each side 16" and mark. Glue and toenail your runners to the 2x6s all the way across. Then flip your floor section over. You are now ready to nail down your flooring once you make sure that everything is level. Prop up with blocks under the runners until level, or else do the remainder of the construction on a surface you know to be flat.
