A very successful Atlanta bird is showing support for its corporate partner in a big way. The Chick-fil-A cows are using Atlanta billboards to congratulate the Atlanta Hawks for their successful season and being the #1 seed in the NBA East. The billboard is just off the Downtown Connector near Turner Field. A spokesman for Chick-fil-A says the billboards are the work of area franchisees banding together to show support from one home team to another. Today is the last game of the regular season…the Hawks are in Chicago to take on the Bulls tonight. They still don’ t know who they will face in the first round of playoffs.
