(Madison, WI) — Wisconsin’s latest bird flu cases are both in backyard flocks. The state’s Department of Agriculture on Friday confirmed a case in Waukesha County and another in Marathon County. In all just 23 birds were put down in the two cases. Wisconsin saw nearly three million-birds destroyed because of the bird flu in the spring. This fall’s return has been much less severe, with just over 80 thousand birds killed because of the flu.
