So I came up with a method (it may already have been invented) of keeping these chickens inside a somewhat closed loop system. I call it “chickenculture”.
So the stand is on wheels and is its own structure. The coop on top is large enough to hold a breeding pair of the sebrights (they are quite small). The chickens eat and defecate into the bin below. The bin below is a vermicomposting bin (I still have to put a bin below it to catch the tea). Inside of it are worms who will eat the microbes that eat the droppings. The worms will make castings which will in turn feed plants (I will plant seeds of probably buckwheat or some other chicken forage). The chickens will eat the plants as they grow up through the bottom. The chickens excrete more and the cycle starts all over.
The inputs are chicken feed, water, worms, chickens, seeds, newspaper and light (from a window).
The process is described above.
The outputs are fertile eggs (good for either hatching or eating), compost tea, worm castings, more worms and heat.
Make sense or am I off in space on this one?
UPDATE: Thanks to Terry on Facebook who reminds me that chicken manure is pretty toxic stuff if its not cut down a bit. I’m not sure how I’ll be able to accomplish that but I have some ideas.
