Originally we got our chickens just for eggs, but since then they've become more useful than we could have imagined... I make as much if not more money on the PHOTOS we take of our chickens as we do the eggs themselves, and they have provided us with insect control, fertilizer, grass control, and are just plain entertaining to have around.
Considering most of the chicks we purchased this year were specifically for the purpose of taking photos of, I probably should have checked "other" as well, but it didn't occur to me until after I'd already voted.
