Backyard Chickens

Backyard Chickens started out as a small site that shared free chicken coop patterns. They still have a growing collection of free chicken coop patterns but now they also have information on keeping chickens, breed information, and much more. They have what might possibly be the largest forum on the web dedicated to raising chickens with over 18,000 registered members and 1,165,089 posts (as of 11/10/08).
