I love my chickens. They really are amazing little contributors to our household. And as long as I have the little amount of feed they require, they will give me fresh emergency food supply every 25 hours or so.
Just about anyone can raise chickens [not necessarily so for roosters- not all cities are super- excited about Koo-koo-roo-koo-kooing or cock-a-doodle-dooing].
Read a few articles online at: My Pet Chicken, or Back Yard Chickens, purchase a copy of Storey’s Guide to Raising Chickens by Gail Damerow, find some chickens on craigslist or local papers where someone needs to find a new home for their flock, get a bag of feed, a shallow plastic basin for water, and you are nearly a chicken farmer!
Of course- there is a bit more to it than that, but not a lot.
The resources above will pretty much guide you through the process, but I will share my experiences with you here, and hopefully pursuade you to welcome a few to your family.
