I've finally gotten around to uploading a few pics of the progress and wanted to post a few so that I have a little diary going. If I never started a thread I'd keep putting it off til I forgot what I did We put it down the hill away from the house and other chicken coops for misc reasons. It will have another very large fenced in area around the whole thing eventually so that they are allowed to free range with the extra security provided by a couple of guard dogs. The pens sit just inside the woods but the large fenced in area will include some pasture with the majority being mostly rocky open forest. Our personal flock of layers would spend all day down in the woods with me if I were there to watch over them as there are sooo many bugs under the fertile forest floor. We have plenty of predators but a pyrenee's can be a chicken owners best investment if properly trained. Sorry for ramblimg..here's some pics... This unit will be 60ft long with 12 pens, each pen will be 5'x4' with a 16'x5' attached run. I wish I would of thought to take pictures throughout the process but... The left side is the back and is ready for doors. The front was left open until the nest boxes/roost poles are in. Looking at the back you can see how I just took a grinder and cut a square out of the tin for the doors. From the front looking at the inside of the back wall.. Hinges are so expensive so I opted for sliding doors. The doors were made by the same tin with some modifications to add some rigidness. Here you can see the strips of wood added on the top and bottom of each door opening. A table saw was used to cut the slot out for the doors to rest in. The doors are not mounted in the following 2 pics. With doors installed and closed. The piece of wood on the outside serves as a handle but more importantly makes the door stiff. There's another on the inside but opposite end that also adds stiffness but also serves as a door stop so that the door won't come out of the tracks. This is the front and the front with the divider walls installed..still have to add a piece of pallet wood across the top to keep each breed totally seperate Suggestions are welcome!!
