Since I can now have legal hens, ... If I have 4 hens (Delaware or similar breed), in a tractor is it necessary to close them into the coop portion at night or can I let them go in and out as they please? I live in the Sandhills of NC and we get HOT summers with nights that may not drop below 90 and thought they might even choose to sleep in the run if the coop were too hot. If the run is high enough is it desirable to have a perch in the run? I like the tractors that have a place to access the food and water from the top rather than having it in the coop or accessing it through the side where the birds might readily walk out while you're feeding/watering. Is it desirable to put a solid roof over that end to keep rain off the feed? For that matter, is a roof, rather than just wire, over the entire tractor desirable or not worth the weight? The birds would be in the shady backyard most of the time though I might put them into the garden to clean up when the squash borers kill the summer squash (predictable and unavoidable in this area). I thought I'd throw a tarp over it for shade then. Would that 4-foot, green wire fencing often used with t-posts in gardens be adequate to contain Delaware hens for supervised outings away from their secure tractor? I want to be able to use them for targeted weed and bug cleanup in places where I can't put the tractor. What if I topped that "playpen" setup with a tarp? How big a feeder would 4 hens need? How big a waterer?
