Thank you for making chickens playable! It's a great concept and definitely leads to mayhem; a welcome addition to no-prep games.
Our story started off fairly sedately. It's unclear why there were shotgun and laser traps for the chickens, or why the hoomans were breeding nazi geese (other than wanting them to literally goosestep). However these were pretty mild compared to what followed.
After a variety of setbacks, all the chickens managed to make the escape and hit all their goals. Revenge was had, the children were flown to safety (miraculously) and the whole place went up in flames (with the power of curry poop). And majestically, from the flames rose the phoenix chicken, to be roasted no more.
I recommend only tracking failed rolls. The drama it creates as the chickens get close to 6 is magnificent.
