I wanted something big enough to raise meat chickens with the ability to be stored in a relatively small space. I happened to have some plywood and old door hinges lying around so I came up with this: We just finished our 1st batch of Cornish-X, 19 all together and this worked very well - though little cramped at the very end. Dimensions 4 X 4 X 4. Materials are 2 1/2 sheets of 1/2" plywood, 8 sets of door hinges, 1 set of small hinges (for the front flap). Took all of about an hour to build, breaks down in a few of minutes simply by pulling the hinge pins. Allows for quick hose down and storage in a small space.
