Regulation

The USDA requires chickens to have IDs.

"The Obama Administration fervently opposes state laws requiring voter identification to cast a ballot. But it is insisting that the nation’s farmers prove the identity of every chicken transported across state lines.
Under the fowl rule proposed by the U.S. Department of Agriculture (USDA), a flock that has been hatched, fatted, and butchered as a single unit may be transported from state to state with a “group identification.” But such groups are as scarce as hen’s teeth.
The vast majority of poultry owners are not part of a vertically integrated commercial operation. They routinely co-mingle chicken stock of varying sources and ages. Consequently, under the rule, they will have to attach sealed and numbered leg bands to every bird they transport."

This is a good reminder that every action government takes makes us poorer. It can't be any other way. Government can only hinder wealth creation.
