Sorry that it's a bit paranoia inducing, that truly wasn't the intent; I find that having all the info helps me deal with the disease in a much calmer mindset.
Most of my past flocks have been made up misfit or rescue hens, and some of the trial and error phase of flock integration got pretty messy and was quite stressful to both the chickens and me. It took me a long time to learn that sometimes the slow way is the fastest way.
