get yourself a few turkeys. they will "vaccinate" your chickens for mereks
Whoops I lied. They are only sold out till Feb for now it looks like! That is a bummer that they dont lay dark dark eggs. They mention it on their website even! I would love to go local for all my day old chicks with specialty breeders BUT since there is the risk of Myreks on my land I want to make sure to get vaccinated ones though, I have a few who are not vaccinated and they are fine. I don't think I want to risk it.
Why are the melanized ones culled? Because they do not meet SOP - youd think there would be a demand for those just because of egg color even if they are not appropriate breeding stock.
