So any chickens that come here, come here to stay. They can not leave except to be slaughtered.
You can still eat the eggs and the birds, though. And honestly I have never lost a bird to it and I don't medicate. they are asymptomatic. I have a very mild strain.

it is just a problem if you want to sell birds or hatching eggs...not ethical to.
