A longtime member of the NC State University poultry science faculty will be hanging up his lab coat in a few months. But to hear him tell it to WPTF's Mike Davis, it's a wonder Dr Frank Edens became a poultry professor at all. ..Professor Edens has been at NC State for 50 years and will begin a phased retirement in July. He was honored by the National Turkey Federation for his work in eradicating PEMS in commercial turkeys in the 1990s.]
