By Serena Maria Daniels DETROIT (Reuters) – A wild turkey is ruffling feathers at the University of Michigan, chasing pedestrians and cyclists, sneaking into dorms and even causing traffic delays by lying down in the middle of streets. The turkey, which has been living on the Ann Arbor school’s North Campus for months, is now the target of a bird hunt because of its aggressive behavior, a campus official said. “The challenge with turkeys is they can become very angry and aggressive,” said University of Michigan police spokeswoman Diane Brown.
