Wow. This article illustrates the law of unintended consequences. Who would have thought that a benign hot-air balloon would become a chicken's mortal enemy?

Abbi Vincent-Lloyd said she lost 30 hens on days when balloons were flying low over her Herefordshire farm.
She claimed the stress of seeing the enormous balloons overhead caused them to run for cover.
