Lower chicken wing prices played a key factor to an increase in earnings, sales and total revenues for Buffalo Wild Wings. The financial results for the restaurant chain's second quarter were announced on July 30.

For the quarter ending June 30, net earnings for Buffalo Wild Wings increased by 41 percent, leaping to $16.5 million for the second quarter, compared to the $11.7 million net earnings for the second quarter of 2012. Total revenues for Buffalo Wild Wings increased 28 percent to $305 million.

Sally Smith, president and chief executive officer of Buffalo Wild Wings, said their strong quarter was not only aided by lower chicken wing prices, but also by the opening of more stores.

Twenty franchised restaurants were also added since the second quarter of 2012.
