The city of Vancouver has an interesting proposal for that city's urban chicken farmers as outlined in this article from the Vancouver Sun bit.ly/alyKEB.
Operation Chicken brings up some very valid points to consider when one is thinking of raising chickens (or currently has chickens).
Like any other living thing, they need daily attention and it is our responsibility to see that they are fed, kept clean and don't become a nuisance to the neighborhood. Our animal shelters are filled with best intentions. I'm certain chickens will start showing up at our local shelter as the "fun factor" wears off.
What do you think about Operation Chicken? Would you be willing to pay a tax to have chickens? Have you thought about what you will do with your hens when they stop laying? Are you committed for the length of their natural lives (8+ years)?
