hi Amos, i think the other most important in this cage is the sanitation of the cage, and every thing in this cage is valuable including the feces/ chicken dung. what iam proposing is let as not just lower the labor or man power consumption but also the possible income out of waste materials. dung management has a robotic/mechanical mechanism that cleans the cages and disinfects. whereas all the gathered dung will flow to the septic tank automatically. and by that we can produce methane gas by designing the tank for collection. secondly chicken manure after methane has been collected can also turn into fertilizers. Now the other challenge is how to put it automatically run by micro-chips also.
