A chicken will be running down through CityCenter Danbury today.  Mayor Mark Boughton will don the costume as part of an effort to address food insecurity.  He's been raising funds for the Feeding Our Neighbors Challenge to benefit 14 area food banks in the Danbury Food Collaborative.  The United Way says Boughton and his public relations coordinator, Taylor O'Brien, will race from City Hall to Danbury Library.  O'Brien will be dressed in unicorn costume.  The challenge, started with 45-thousand from 3 local financial institutions, has brought in a total 81-thousand dollars.  Boughton raised about 54-hundred dollars while O'Brien brought in 66-hundred dollars. The “Feeding Our Neighbors Community Challenge” has a goal of raising 100-thousand dollars.  It was launched after comedian John Oliver donated 25-thousand dollars to the Connecticut Food Bank as part of a back-and-forth with Boughton.
