Things we learned on last night's run:
* Chickens can take the boat from Lossarnach to South Ithilien to void taking damage from the Anduin. (Regular players can swim across at that point without taking damage and at some point I'd love to see if chickens can do the same, but we were playing it safe.)
* Chickens can run right up to the Black Gate without taking damage. Seriously.
* They don't take damage from the waste water in the Slag Hills, either.
So we have proof of concept for a "chickens to Mount Doom" run, pending what we find when the release drops and the gate opens.
And the chickens await.
