❗️MAREK’S PSA❗️
I recently had a past customer reach out to me, that she was losing my birds and suspected Marek’s. Now this purchase was months ago, and the birds were older growouts, this was not a recent purchase. But still, naturally my heart sank with even the thought that it originated in my flock.
Now I have not had any sick birds, weird neurological behavior, or mysterious deaths. But for my own peace of mind and for all of you, I paused my sales and submitted samples. I sent out environmental/dander swabs, oral swabs, and blood samples in my main coop (which would be the birds that were both parents as well as previously housed with the suspected birds), and also my transition pen and my growouts - because at that point I might as well test them all for good measure, right?
Results came back today, and my flock is NEGATIVE in all coops.
I wanted to post this here for all of you, and for myself and my name.

A few notes about Marek’s:
1️⃣ “Marek's Disease is by far one of the most common illnesses in small flocks and not treatable once the clinical signs have begun.
The percentage of illness and death in a flock can be anywhere from 1% to up to 50%. The clinical disease is typically seen between 6 weeks to 30 weeks of age. But Marek's Disease can develop in older birds as well.” -Penn State
2️⃣ It is spread via dander from infected birds most commonly, but can also be spread via clothes, boots, carriers that go to other farms, wild birds, etc.
“In general, poultry diseases are highly contagious because they do not require direct contact between birds, or even between locations, to spread. With Marek’s disease, a tumor-forming virus, the disease can spread five miles in the air without a carrier. That radius increases once you account for the activities of native backyard birds, or your own shoes if you run to Tractor Supply after you clean the coop, etc.” -Tri-State Vet Services
3️⃣ “Since infected birds are shedding virus, they will spread the disease as long as they are alive. If new, unvaccinated birds are brought into an infected flock, they will also become infected. This is especially true of young chicks that are highly susceptible. Even if new birds are quarantined away from the affected flock, caretakers can carry the virus-laden dander on hands, clothing, shoes, hair, and skin and spread the illness. One way that Marek's Disease is not acquired is through the hatching egg.” -Penn State.
❗️An added note to this: my chicks and birds ARE NOT vaccinated, so if a flock has vaccinated, asymptomatic carriers, birds from my flock will be more susceptible to symptoms and death than the vaccinated birds in the same area.
The reason my flock is not vaccinated is because the Marek’s vaccine is sold in LARGE hatchery amounts, and must be used within hours of mixing it up and the rest is discarded. So when I’m hatching maybe 10 chicks at a time, a vial for 1000 birds is going down the drain each time and it is unfeasible for small breeders, unfortunately.
4️⃣ Also important to note, that if you’re ever losing birds and suspect Marek’s, you can submit the whole deceased bird for a necropsy. As I was not losing any birds, and personally was not keen on the idea of culling a perfectly good hen, I submitted the dry swabs and blood samples instead. But you can submit the whole bird if you ever find yourself in this situation at home (hopefully not!).
If you’ve read this far, I hope you’re having a great day! And When In Doubt, Send It Out! 😄
