So, you want to keep backyard chickens? You’re reading all you can to learn what you need to know to get started, you have bought all the books and are scouring the Internet hoping to absorb the most important information. That's a great start, but some lessons are painful and expensive to learn by experience, so in the hope of sparing some growing pains for those about to embark on chicken-keeping, I have asked my Facebook fans what they wish they had known before they began keeping chickens.
