Chooks can autorotate quite well . . . .

( but RPM is critical in the oven. )

Authenticity not guaranteed:
There is a story that in the early days of missionary aviation the pilots in PNG had a system of launching hens out of fixed wing aircraft to stock the villages below. To overcome the damage that might occur with wings meeting slipstream the hens were in paper bags. Once ejected they struggled and ripped open the bag and fluttered safely to the ground.

Authenticity guaranteed:
In more recent times this was discussed by some mates in a bush camp in the same country. It was decided a trial was the way to check it out. A chook was bought from the local village and taken up in a Bell 206L, and launched, sans paper bag. To their surprise the chook plummeted to its death. The wonder then was if it was just that particular chook that had failed?
However, research was quickly curtailed. The PC management of that particular energy project heard about the incident and some castigations, with threats of dismissal, were administered to the 'researchers'. I guess we wont know until someone else on these pages continues the research for us.
