This has got to be the strangest story to release on April Fools day:
Today the United Kingdom declassified information confirming that in the 1950s they had worked towards developing a Nuclear Device that used a live chicken as one of its key components. The nuke in this case was used as a mine to prevent the advance of the Soviets if WW-III were to break out. The Nuke in question was very sensitive to cold weather. The solution that our tea-drinking hat-wearing brethren came up with was to stuff a few live chickens inside of the nuclear device to keep it warm enough to operate properly. Everyone is swearing up and down that this is not a hoax.

On a side note, the US Air Force considered using live chickens to steer the B-52 launched cruise missiles. However, it turns out the chickens weren’t able to attain the requisite ‘Top Secret’ security clearance so the project was scraped. ;)
