We hatch birds at our house to add to our flock and we also get some that are not vaccinated. Over at my grandparents house there is an outbreak of mareks disease. We gave her hatching eggs and three of them hatched. One is dead from mareks, another my grandma bought died, and one of the first of the flock also went. None are vaccinated accept one and very few of ours at home are vaccinated as well. Also, can bantams be vaccinated?
