Iowa Public Radio: The bird population at the nation’s largest producer of peacock hatching eggs is taking a hit from this long stretch of cold weather. It will take years for the numbers to come back. Dennis Fett operates the Peacock Information Center in the Pottawattamie County town of Minden. He was beginning to recover from a tornado that hit two years ago and killed around 100 birds when the cold snap hit, sending temperatures below zero over the past two weeks. Fett says he only has around 70 peacocks still alive and it will take some time to rebuild the population.
