Well, chickens do poop out useful things like eggs.
The same hole poops out other stuff.

Chicken Trivia: It takes about 24 hours for an egg to make the journey from ovum to vent. Coloring of the egg is the last step and determined by genetics. Brown, white, green...the egg inside is exactly the same until they get to the spray paint department.
DUmmie Trivia: Despite the above fact, DUmmies will still pay more for brown eggs than white eggs. Put the word "organic" in front of that (aren't ALL eggs "organic") and you can double the price.
