Lining your coop and ventilation
Create a window on the opposite side of the door (important for ventilation). This window measures 200mm by 500mm and does not get lined. You may cover it with chicken wire if you wish.
Use two full lengths of the corrugated PVC on the roof. You should be able to overlap by two corrugations and still have a slight overhang at each side. There will also be a slight overhang at each end.
Pre-drill holes for the flat head roofing nails and attach at regular intervals to the roof frame.
Important: the nails should be placed on the convex bits of the PVC (the bits that stick out). Don't squash the pvc by nailing too far. This ensures water doesn't get into the nail holes.
Also important: Rain water will run off each end. Run a line of silicon under the edge of the roof at each end. This encourages the water to drip straight down and not run around the edge and into the coop.
Cut the remaining corrugated PVC sheets exactly in half width ways. There should be enough to go right around the outside of the coop with some overlap. There will be three half sections on each long side of the coop and two on each end (ten in total).
Nail in the same manner as with the roof. You can just make out some of the nails in the photo (they have been painted).
Note that in the picture, the lining is covering the window. We found it easier to put the lining on first and then cut out the window, to make sure it was straight.
Paint the outside walls of your coop with a plastic primer and then two coats of an exterior paint of your choice.
Congratulations, you are done.
