I just got this book at a farm store near me. The book is called The Chicken Health Handbook 2nd Edition A Complete Guide to Maximizing Flock Health and Dealing with Disease by Gail Damerow. Great book! Luckily i have not had to use it for any illnesses in my flock but is great to have on hand. It is about an inch thick and has tons of information, graphic pictures, cures, natural approaches to enhance immune system, and a lot of other information that any chicken owner would be glad to have. You can buy it on Amazon. I love my copy and give it a five star review!
