This story is absolutely brilliant. From the online version of the Wall Street Journal, the first couple of paragraphs speak for themselves:
Hobbies often hatch small-business ideas. Chickens are no exception.
Ruth Haldeman began adopting pet chickens in 2002. "I wanted fresh eggs, but I found that chickens are like peanuts, you can't have just one," she says. Before long, Ms. Haldeman had founded ChickenDiapers.com in Hot Springs, Ark.
"Everyone was talking about how there was a need for diapers," she says, given that chickens typically can't be potty trained. "Oh, lord, what a mess they make."
I think this is brilliant, well, because it is about diapers you put on chickens. Secondly it is a great example of what individual entrepreneurs can do if they see a need (or a messy niche) and have the economic freedom to take the initiave and fill it. You may not need very many chicken diapers, and I find them hilarious, but you have to admit a command and control economy would never have room for un-housetrained chicken potty accessories.
