Other chicken-keeping perks include: free, organic pest control (they love slugs!), kitchen waste removal (see a list of what they will eat here) and wonderful fertilizer for your garden from composted poop.
Seek out attractive digs. The look and feel of your coop can be incredibly important in keeping the peace with neighbors. You don't need to spend a fortune on a designer coop if you don't want to, but do pay attention to how it will fit in with other structures in your neighborhood. We found a low-profile A-frame chicken coop on Craigslist and with a fresh lick of paint ended up with a cute coop on a budget.
