The pallets are 6' x 4'5" I'm planing on adding some half pallets to the side wall to make the slant roof 2' higher. I picked up a window from trash day that still works good but the guy was replacing all of his windows and told me that was the best on. Most of the material's were free. I'm trying to be as Green as possible. I don't have the front wall up yet so its still shaky , Not very stable yet. I'M not sure if the roof will make it stable ?
adding a few boards that overlap the connections of the pallets would strengthen it a good amt. I would also ad 2x4s as top plates would help tie in the roof too. looks sweet
To take some of the wobble out of your structure, you might want to build your roosts in the corners or get some turnbuckles.
A scrap piece of wood can also work (you simply wrap your wire around the board and twist the board to snug up the wire (sorta like those toy airplanes with the rubber band propellers...snug it up and then just nail it to the wall)
I would tie the front in with 2x4's and make a door to access the coop from the outside. If you can get more of those palllets break them up (carefully, as the pieces can be used for trim and other things) and use those 2x4's for your framing. Pallets are so much fun to use, and it gives you something to do.
