When bison roamed the Great Plains, prairie chickens and other fowl played an important role as the clean-up crew. They would follow the herds feasting on the larvae in bison manure.
In Doug Darrow’s 160-acre mob grazing system near Oxford, Iowa, his 300 chickens have the same job, but they ride in style from paddock to paddock in an old school bus that doubles as a chicken coop. “This means there are fewer flies to pester the cows,” said Darrow. This natural form of pest control, improves herd health and rate of gain, while providing another income source from the eggs laid by the clean-up crew.
