A landscape designer and cancer center "paper pusher" say chickens are a great way to till gardens -- leaving behind valuable compost and a wealth of eggs.
Seattle limits chickens to three on a typical single-family lot, the Seattle Post-Intelligencer reported.
That is plenty, say Carlson and Farley, who tout a coop that lets the chickens claw gardens into fertility.
Farley said his chicken interest began as a child in San Francisco, which "lets me tell the classes I teach that I've been raising chickens for most of 50 years -- as if I was some sort of expert."
Carlson, a chicken gardener since 1979, keeps most of the eggs.
"Their eggs are so excellent, they taste like butter," Carlson said.
