Mate, I honestly didn't know if you were taking the mick or being serious, but after doing some research (yes, you made me google whether chickens could survive being dropped out of a plane) I must confess this is a damn good idea!
Just to contribute something valuable to the discussion, I think you could also include cats in a follow up drop. Obviously dogs would be better pets, but dropping dogs out of a plane would be cruel. My research led me to the understanding that cats, like chickens, have a very low terminal velocity. That said, I think the plane would need to swoop a little lower on the cat drop.
But cats aren't as tasty as chicken.
BBQ cat legs with some hot sauce, anyone??? Ewwww, I'd rather starve......haha
I know right? Everyone talks about cats.
I googled chickens dammit!
