Some chains buy them from suppliers by the pound, then sells them to the consumer in fixed numbers of wings.
The new method downplays the actual number of wings in each order. Instead, it presents variable-size portions based on weight.
Because the wing sizes have gotten so much larger, five wings yields more ounces of chicken than six used to. So the guest is seeing a value in additional protein.
The move is essentially a price increase. But it’s probably a more conspicuous price increase than any other you could take because it does change the way the consumer interacts with the concept.
