The invention relates to the field of chicken breeding devices, in particular to an agro-ecology egg laying device for free-ranging native chickens and a using method of the egg laying device. The device comprises a base, a gravel pond, a filtering screen bracket, a drying area, a chicken coop, a cleaning device and a motor assembly, the gravel pond is fixed to one side of the base, and the filtering screen bracket is arranged on one side of the gravel pond; the drying area is arranged on the lower portion of the filtering screen bracket, the filtering screen bracket and the drying area are arranged between the gravel pond and the chicken coop, and the chicken coop is fixed to the upper portion of the base; the motor assembly is arranged on one side of the chicken coop and arranged on theupper portion of the cleaning device, and the cleaning device is arranged on one side of the chicken coop and fixed to the upper portion of the base; the gravel pond is rectangular, the bottom of oneside of the gravel pond is fixedly connected with one side of the base, and a pond cavity is formed in the gravel pond; the section of the pond cavity is in a concave arc shape, a water discharging pipe is formed at the bottom of the pond cavity, and the pond cavity is filled with a gravel layer. The device is simple in structure, the surfaces of eggs laid by native chickens are clean and cannot be contaminated, and the phenomenon that on rainy days, shells of eggs laid by the free-ranging chickens are contaminated by mud on chicken claws is avoided.
