Neverwinter Nights Easter Egg - Chicken in Beorunna's Well

The chickens in NWN have been used by BioWare as a vehicle to add a joke into the game. If you "observe" (ie. right-click) the chicken to get it's full description, some chickens will be described in the standard way, but in other cases, the description will read something along these lines: "This poor animal has it's eyes avidly set on the road ahead, and you can clearly see it's intent to get to the other side (etc)".
