For this reason, it is desirable that the sensor is fixed to the egg collection belt installed in each of the multiple cage rows, or is installed so as to be movable along the egg collection belt. If the sensor moves along the egg collection belt, the sensor may be configured to detect the condition of the egg-laying hens in the cage.

Therefore, it is desirable for the abnormality detection unit to detect an abnormality in the specific cage or cage row based on cage row information including information on the laying hens housed in each cage in each of the multiple cage rows, in addition to the information obtained from the sensor.

With this configuration, for example, the transport operation of the egg collection belt can be performed while avoiding the peak egg-laying time period of the egg-laying hens.
  • the comparison group in the abnormality detection unit 34 in the above embodiment is a plurality of cage rows 12 provided with egg collection belts 14 that start and stop at the same timing, but the comparison group is not limited to this.
  • the comparison group may be cages 11 or cage rows 12 at different height positions in the egg-laying hen house 10 (e.g., upper floors, middle floors, and lower floors, etc.), or cages 11 at different positions or areas in the longitudinal direction of the cage row 12 (e.g., upstream, central, and downstream, near the air inlet, central part of the hen house, and near the air outlet, etc.).
  • multiple areas in the longitudinal direction of the cage row 12 may overlap each other.
  • the comparison group may include cages 11 or cage rows 12 of different egg-laying hen house 10.
  • the comparison group may also be a plurality of cage rows 12 provided with egg collection belts 14 that start and stop at timings that are shifted by a predetermined time.
  • the senor 2 is provided at the downstream end of the egg collection belt 14, but it may be provided so as to be movable along the egg collection belt 14.
  • the sensor 2 may be provided on a traveling cart (not shown) that moves along the cage row 12.
  • the traveling cart is provided with a feeder (not shown) that feeds food into a feed trough (not shown) provided along the cage row 12.
  • the sensor 2 is not limited to a configuration that detects eggs on the egg collection belt 14, but may be a configuration that captures an image of the inside of each cage 11 to detect the condition of the egg-laying hens.
  • the position information may be obtained from the travel distance from the starting point, or may be obtained by providing a position display unit (not shown) such as a QR code on the cage 11 and reading the position display unit with a reading unit.
  • the egg sensor 2 in the above embodiment detects eggs on the egg collection belt 14, it may have the configuration shown in FIG. 7.
  • the egg-laying chicken house 10 shown in FIG. 8 is equipped with a collection belt 19 that collects eggs E from multiple cage rows 12 for each cage row 12.
  • This collection belt 19 is connected to multiple egg collection belts 14 and collects eggs E from multiple egg collection belts 14.
  • FIG. 8 shows a configuration in which eggs E from a total of four cage rows 12, two rows in front and back and two rows above and below, are collected.
  • a connection belt 191 is provided between the collection belt 19 and the egg collection belt 14 as necessary.
  • the collection belt 19 has transport areas R1 to R4 corresponding to each cage row 12.
  • This sensor 2 can be a camera that can capture images of the eggs E (the transport regions R1 to R4 corresponding to each cage row 12) on the collecting belt 19 all at once.
  • the abnormality detection unit 34 detects abnormalities in a specific cage 11 or cage row 12 based on the image captured by camera 2.
  • the number of apparent sensors can be reduced by making the pixel areas of the image captured by camera 2 correspond to each cage row 12.
  • the abnormality detection unit 34 in the above embodiment detects an abnormality in a specific cage 11 or cage row 12 by relatively comparing the multiple cage rows 12 included in the comparison group, but in cases where there are a small number of cage rows 12, in addition to this relative comparison, an abnormality in a specific cage 11 or cage row 12 may be detected by comparing with previously prepared reference information or past data.
  • previously prepared reference information include the standard number of eggs laid.
  • the control and calculation device 3 of the cage abnormality detection device 20 in the above embodiment may be integrated with the control device of the egg-laying hen house 10 to configure the egg-laying hen house 10 and the cage abnormality detection device 20 to be controlled collectively.
  • the present invention allows for quick and easy detection of abnormalities in a particular cage row or cage by relatively comparing multiple cage rows.
