Do you have a pic? Trying to picture it. Wait is it like a chicken tractor just larger?Wooden, open air a-frames. Ours have to be moved with a vehicle (tractor, riding mower, truck). Our large ones run 8x10 ft with a peak over 6 feet tall so we can stand up inside them. Even our small 3 foot tall a-frames for single male housing does well. The wide base gives it a lot more wind resistance.
