Agriculture Department spokeswoman Christin Kamm says a case of avian flu was discovered at a recent bird sale and traced back to the quarantined herds of chickens, pheasants or quail.
Officials say the strain of avian flu found in these birds rarely affects humans.
All other birds within a two-mile radius of the affected flocks will be tested for the disease.
Kamm says the quarantined flocks are not part of commercial poultry operations. The birds are being raised either for limited sales, personal consumption or county fair competitions.
