We lived in town so chickens weren't an option. If I were setting up a retreat I'd go with chickens. They'd supply fat and eggs as well as garden pest control. Of course around where I live now feral pigs are a huge problem (and wonderful source of food).

Not sure how your city is, Blast. I grew up in Anaheim, CA, and some neighbors had a chicken coop. I'd have never known if I didn't get into their backyard one time. Probably about 20 chickens they had, and quiet as could be... That being said, check your city ordinances!
