The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.

step 2, obtaining the real-time total weight of the laying hens in each coop, determining the average weight of the laying hens in each coop according to the real-time total weight, and displaying the average weight in real time so that a feeder can determine the feed feeding amount and feeding frequency for feeding the laying hens according to the average weight;
and 3, acquiring real-time growth time points of the laying hens in the coops, determining the growth cycles of the laying hens according to the time difference between the real-time growth time points and the initial growth cycles, and irradiating the laying hens in the coops with light when the laying hens reach a preset growth cycle.
7. A laying hen feeding method according to claim 4, wherein in the step 3, the illumination direction is determined in accordance with a tilt direction of each of the cages.
8. A laying hen feeding system, comprising:
the gravity detection unit is arranged at the bottom of the coop and used for detecting the total weight of the laying hens in the coop in real time;
the display unit is used for displaying real-time data of the weight of the laying hens in the coop;
the illumination unit is used for providing illumination for the laying hens in the coops;
the control unit is electrically connected with the gravity detection unit and the display unit and used for receiving total weight data of the laying hens in the coops, calculating the average weight of the laying hens in the coops according to the total weight data, and sending the average weight to the display unit so that a feeder can determine the feed feeding amount and the feed feeding frequency according to the average weight of the laying hens in the coops;
the control unit is electrically connected with the illumination unit and used for controlling the illumination unit to provide illumination for the laying hen when the laying hen reaches a preset growth period.
9. A laying hen feeding system according to claim 8, further comprising: the inclination angle detection unit is arranged at the bottom of the coop and used for acquiring the real-time inclination direction of the coop to determine the gathering area of each laying hen, and adjusting the irradiation direction of the illumination unit according to the gathering area of each laying hen, so that light rays are directly opposite to the gathering area of each laying hen.
10. A laying hen feeding system according to claim 8, wherein a clock module and a processor are provided in the control unit; wherein,
the clock module is used for sending a real-time growth time point of a laying hen to the processor, so that the processor determines a growth cycle of the laying hen according to a time difference between the real-time growth time point and the initial growth cycle; the processor is electrically connected with the illumination unit to control the illumination unit to be started when the laying hen reaches a preset growth period.
