The invention relates to an intelligent free-range chicken free-range system, which comprises coops, guardrails, mouse expellers, electronic foot labels, weighing devices and a controller. The coops are distributed on a free-range land. The guardrails are arranged around the free-range land. The mouse expellers are distributed around the guardrails and the coops. Each electronic foot label is provided with a timer, a positioning module and a communication module, and is detachably arranged on one foot of a chicken and is connected with an entrance guard system of one corresponding coop. Each weighing device is arranged under the corresponding coop. The coops, the electronic foot labels and the weighing devices are all connected with the controller. Chickens enter the corresponding coops when the electronic foot labels trigger the entrance guard systems of the coops, in this way, the number of each coop where the corresponding chicken enters can be obtained. The weighing devices automatically send the weight of the corresponding chickens to the controller, so growth situations of the free-range chickens can be monitored in an intelligent manner. If one chicken stays in a position over 15 minutes, the corresponding electronic foot label will automatically send position data to the controller, and the controller conducts path planning on the position data and then notifies workers of collecting eggs. Therefore, the eggs of the free-range chickens can be collected quickly.
