I did some figuring and not including labor or the coop, feeding my six chickens is cheeper then buying similar quality eggs at the store. Plus I save a lot of money on fertilizer and my garden yields are better because of all the grasshoppers they eat.
I ate breakfast at a little diner a couple weeks ago and was served two over-easy eggs on hash browns. Normally, I'd consider this comfort food, but I was completely disgusted with the "fluorescent yellow" color of the yolks and the flavor was kind of "canned" or something. I'm sure the eggs would have been fine for most chickenless folks, but after having chickens I will never be satisfied with commercial eggs again.
I'd like to see a future with chickens on every street in America.
