It is estimated that a 1.8 kg chicken will produce 28 to 100 grams of manure per day or 12 to 36 kg of manure per year. In its lifetime, a chicken can produce enough manure to power a 100-watt lightbulb for 5 hours. The manure produced by chicken can be decomposed to produce methane, which in turn can drive turbines to produce electricity. In fact in Britain, Mr. Harold Bate has invented the car that runs on methane produced from chicken manure.
