After the initial coop framing, today was spent adding the back, sides and floor to the coop.
The back is a complete door, secured with two strong galvanised hinges and a galvanised bolt. The door was made oversized, then cut down to the exact size with a table saw, and covers the entire back of the coop with about a 10mm overlap on each side to keep out drafts. The front will have a smaller lockable door and to make things simpler I used 2 pieces of 150mm wood attached to the inside side of the front with the door in the centre of these. The floor is a 600mm x 600mm piece of exterior grade plywood, with notches cut out of each corner to accommodate the framing material, then screwed together. It’s starting to look like a coop!
