Some time back, BYC had a chicken tractor on its site, suitable for 10 chickens. It was easily moved from place to place on detachable wheels, so fit well with the permacutlure concept. Best of all, it required minimal materials and you could even stand up in it! It was called the JA-17 Poultry Mobile. I bought the plans and built one, and am still using it - I discovered it's INTERLOCKED constrcution made it quite rugged. It even makes a decent small greenhouse. It could possibly be the ultimate chicken tractor. Now I see it's missing from the site and I was wondering whats up. Did anyone build it, or even remember it?
