You have to move the "tractor", and the fence, every three days. You have to "train" the chickens not to roost under the tractor.
The chickens are probably miles away from you at times. The fence is short. There is no overhead protection.
Saftey: 0% (even though it has a fence... really, it only takes one raccon, or one dog... or a few hawks or even crows)
In most places around the US you would have to have two chicken coops, the tractor and another one for winter. You have to pay for fuel to drive over to your tractor and pull it. You have to buy an electric fece (large), you have to have batteries to run it.
Expense: 300% of norm
Quality of life for chickens:
About as good as it gets... until they are eaten by you or the birds. 100%
