Ive been working on this for a bit - visiting this website and reading stuff to try and get a feel for what I need, cause Ive never had chickens before. Its actually a tractor. At least that was the plan. Right now a good name for it would be the lead sled, because of the extreme weight. But, I think if I put detachable wheels on the back, Ill still be able to scoot it around. The coop is 4 by 4. The run is 8 by 4. Its just barely big enough for 4 chickens, but thats all I want. Obviously I borrowed the whole setup from those chick-n-barns. I worked on my own design - a kind of pyramid shape with an enclosed run below it - but it just wasnt that practical. I thought this had a look I could live with and was certainly functional. The small door on the back pops off for a clean out. Just place a bucket or shallow wheelbarrow below it to catch all the composting goodness. Below that, the fencing in the back is stretched over a removable frame to let the girls out if you wish, or allows you to throw some choice morsels in there that are too large to drop through the gaps in the wire and enables cramped access for crawling humans. The inside isnt much to see. A roost runs full length one side, and two nest boxes are situated up high on the other. The roof of the nest boxes is actually the roof of the coop - just swing it up to access. The threshold of the door is about three inches above the floor, making room for a layer of woodchips or whatever. Finally. A picture of the coop without the run attached. The cost was probably around 120 dollars or so.
