I'm currently working on a small book designed to help diagnose, prevent, and treat medical issues found in backyard chicken flocks. I have it divided up into diseases, injuries, and other physical ailments, and at this point I feel like I've got most of the major items covered. However, I'd love to hear from other chicken owners regarding what seems to pop up most often in your birds, and the more obscure troubles that took you forever to diagnose. Heck, if you'd like to weigh in on what you would want to see in a first aid book for small flock owners, I'd love to hear that as well. Any input would be greatly appreciated!
