A chicken tractor is essentially a chicken coop on wheels. It consists of the traditional wooden frame with wire mesh for walls and roof, but unlike other stationary coops, can be dragged across your yard with an attached rope or chain. This allows you to control where your chickens roam and fertilize by dragging their shelter from one location to another throughout the day.

A chicken tractor is a mobile hen house that can be moved around a garden or plot of land in order to allow the hens easy access fresh grass which they will eat and also fertilize the crops or the lawn with their droppings.
