I adopted adult chickens and brought illness into my first flock because of my own ignorance. I tried treating with medications and weighed the pros and cons of treating 16 birds versus starting over. The state NPIP inspector was scheduled to test my flock yesterday to see exactly what we were dealing with. Two days ago, dogs killed 14 of my 16 birds. I have two chickens, one with Coryza that survived and another 6 month old pullet that has to be put down tomorrow so I can have a healthy flock. It was not an easy choice. How many of you have had to start over due to illness or tragedy?
