A Homemade Egg Mobile is basically a chicken coop on wheels (or sometimes on skids) pulled by tractor, utility vehicle, or pickup truck to different parts of a pasture. Laying hens are let out during the day to free-range then shut back up in the coop at night to roost and lay their eggs. Generally, an egg mobile is relocated once a week or so, often to an area where livestock had pastured a couple weeks before, to feast on fly larvae around the dried droppings as well as on insects and seeds. Their free-ranging can be limited by portable electro-net fencing to keep them somewhat corralled while preventing intrusion by predators. A portable waterer should be placed within the fenced area. The birds instinctively return to the coop at night.
