[PROBLEMS] In the existing cages for breeding stocks, hens have a habit of laying eggs at the four corners. As a result, it is found out at present that the feces of the hens huddling together makes it difficult to obtain hatching eggs of good qualities and the egg breakage rate is elevated. In addition, it is also found out that a hen cannot get a relaxing place (i.e., one of the four corners) has only a lowered possibility of egg-laying and thus hatching eggs of good qualities can be hardly obtained because of these factors. Thus, it is intended to propose a clean, highly efficient and novel cage for breeding stocks wherein laid eggs, which are liable to huddle together at the four corners, can be dispersed. [MEANS FOR SOLVING PROBLEMS] A rectangular cage composed of a floor part designed to allow free migration of hens and an outer circumferential part showing good ventilation almost allover the periphery, wherein multiple partitions are provided across the narrow space above the floor part and these partitions are provided with a visually blocking panel so as to provide relaxing places similar to the four corners to hens.
[PROBLEMS] Among the components of a vertical feeding device for egg collection, particularly egg placement means has a problem of holding an egg for an unnecessarily long time period. In such a case, the egg held drops at a position outside an expected place to sometimes contaminate the egg placement means again, further contributing the egg placement means to hold an unnecessary number of eggs and putting the device in unsanitary conditions by scattered eggs. [MEANS FOR SOLVING PROBLEMS] The invention relates to an egg collection conveyor and a vertical feeding device for egg collection, and particularly relates to an egg roll out mechanism for an egg collector. The egg collection conveyor collects eggs produced at each cage of a multiple-stage chicken cage and conveys the eggs to horizontally one end side of the conveyor. The vertical feeding device for egg collection is provided on one end side of the multiple-stage chicken cage, conveys the eggs in the vertical direction, and discharges the eggs, collected by the egg collection conveyor, at a previously set position. The vertical feeding device has egg placement means on which eggs are placed and that discharges the eggs at a desired position. The egg placement means has a space section directly under the position where an egg is placed and the space can be in contact with the bottom surface of the egg. The vertical feeding device is connected to an endless conveyor for conveying the collected eggs to a desired position. A projection for egg roll out is provided on the downstream side of the egg placement means and the distance of the projection relative to the egg placement means is changed corresponding to a change in the conveyance direction of the endless conveyor. In the egg roll out mechanism, when the relative distance is minimum, the egg roll out mechanism causes an end of the projection to reach the space section to help rolling out of an egg.
