After owning several ducks in rl (until I got tired of the bastards and gave
them away), I think duck race needs tuning to become more realistic:

Ducks should eat themselves to death if they come upon a heap of food more
nutritious than grass, and nobody restrains them or removes the food.

If a duck walks into a room with food, it should be unable to move on (unless
attacked) until all food is eaten.

Anybody that spends more than a couple of minutes in a room with a duck thats
not currently eating or asleep should have some sort of check every 10 seconds
to manage to not attack and kill the damn thing to stop the incessant
quacking.
