This is a well written, well structured, and well supported article on the potential financial costs and benefits of keeping chickens. It works systematically through the type of costs you will incur, and gives advice on how to reduce them by taking a few simple steps, such as buying feed in bulk. It then turns to potential sources of income from a flock, with good advice and plenty of tips and hints on how to succeed via the different routes. There are links throughout to other pages in BYC where relevant matters are discussed and issues of interest can by pursued further.
