I am in the middle of designing a GPS guided chicken rover that you as the owner can go out and pick as many points (within reason) that the rover (moving henhouse) will go. It will travel to one point (coordinate) then the next allowing you the opportunity to pick the areas that the chickens range on. Key to the design is that the chickens are encouraged (fooled) into "following" the house. The rover stops at night, and sometime after dusk the door closes. It opens at first light. The GPS system tells the door , based on its coordinates and time of day, when to open and close. The question is given that it is silent and its movement is imperceptible to the chickens, how far will they go with it? They think that they are staying close to it but they will be actually moving. Is this too far out there as an idea? The rover is self sustaining as it is both a water collector (100 gallons) and has solar power and batteries. It has the capability of lights at night and can accomodate other eletrical needs. I am debating whether to make it small (30 chickens) vs. large (200 chickens). the idea being that 3 of these could cover more territory than one. The main goal of this is to follow cows, sheep and goats on a rotational pasturing system. It allows for healthier chickens and helps to build topsoil by putting the chickens close to as many cow patties as possible. However, it would work even without the other animals as it encourages the chickens to move about and be safe close to their house. Any suggestions from anyone?
