    8 months ago I had an 11 year rooster contract Marek. He died. The rest of the flock was uninfected. My vet said they probably got it from wild bird, since I don't breed and had not adopted new chickens.
    3 weeks later I did adopt a new chicken and she contacted Marek also. Luckily with intensive treatment she fully recovered.
    When will it be safe to reintroduce new chickens? Or is this now for life?

    Welcome to BYC. If you have Mareks on your property from one sick bird, then the disease will be on your land for many years-seven is a figure that I have read, and it may last longer. It is spread in the dander and dust which basically goes everywhere. You can't clean or disinfect for it. Did you have your Mareks confirmed with testing or a necropsy, since many other diseases can appear to be Mareks? Any new birds you add should have a Mareks vaccine, and it will take 2 or more weeks after vaccination for the new ones to develop full immunity. Here is a good article to read about Mareks disease: https://www.backyardchickens.com/a/the-great-big-giant-mareks-disease-faq

    Hi,

    No there was no necropsy. But two birds got it and the vet (a birdspecialist ) confirmed Marek. In Belgium a hobby birdkeeper cannot vaccinate against Marek. There is no way to get a vaccin. Only the intensive farming industry can vaccinate. So I was thinking of adopting a ex-laying hen. Is a vaccin safe?

    Thanks alot for your reply!

    The Marks vaccines are very safe. Since you have Mareks on your property, any birds, whether vaccinated or not, will become carriers, although the vaccinated chickens should not have symptoms of the disease. Any hatchery chicks of mine always get the vaccine.
