Welcome to BYC. My friend has had silkies for many years, and then added seramas. It turns out both breeds have no resistance to Mareks. She ended up losing her last 3 birds to that.
They died a day apart.
BTW they were house chickens all their lives but, she allowed the silkie outside because it didn't fly. Silkie brought the disease inside with it.
They died a day apart.
