Many amateur chicken enthusiasts make their own chicken coop tractors. Many plans are available online or in books. Plans can vary a lot in size and level of construction difficulty.
Chicken tractors make it easy for even those with small yards to raise a few chickens. A chicken tractor consists of a pen with no bottom that can be moved over an area in order to allow chickens to forage. They have become extremely popular in urban centers as many towns have eased regulations to allow residents to keep some chickens for fresh eggs. A small percentage of growers also raise the chickens for meat.
