Since peasants reproduce like rabbits, I figured that would mean chickens reproduce like viruses. So, chickens will be around for a long time.
Then again, I bet it'd be a comedic death for Fred as a hero. Come to think of it, De-Legro, would you like to be Fred's executor? Meaning, you give out the last RP to all of Arcaea if and when Fred dies in battle. I figure it'd be lols to RP the chickens across the continent celebrating at the death of their nemesis Fred the Consumer.
We can do a RP exchange, that way if Carlos ever actually dies from being a Hero (something I've pretty much given up on) you can send his last RP. Have you considered that perhaps when Fred dies, the chickens will deep fry him?
