Sorry I don't know how temporary it will be. I would have to think it might be a seasonal event. Eventually the virus will die off with most of the wild birds affected by it. Until then, keep your birds safe.I just wonder how temporary, though, you know?
I admit I'm feeling a little discouraged. One of my best hens just died a few minutes ago. It's been a rough week.
I do remember Newcastle lasted about 4 to 6 months. It ended on the month of June. When the weather got really warm.
