That is sad news! However, is it even possible for them to show signs of Marek's at such a young age? I thought it took six weeks for the virus to replicate in the chicken and then start to show signs. Maybe it is something simpler like Coccidia.
I always vaccinate and almost always buy vaccinated, But, what do you do if you really need an older chick that you have finally found and it hasn't been vaccinated???
My interpretation was that each of the above events begins when the previous one ends. So 7 days + 10 days + 7 more days + 3 weeks = approximately 6 weeks (or more) for the bird to start showing signs of illness.Yes, if the chick is exposed at hatch, three weeks is enough time for signs to show. It is not common and most start to demonstrate signs a bit later on, but it's not impossible. Six weeks just happens to be the time that a lot of birds show it, but it takes much less time for it to actually be a problem in some birds. From the time of exposure:
Reference: http://vir.sgmjournals.org/content/86/11/2989.long
- Approximately 7 days: Virus latency (meaning the virus has now stored a 'blueprint' of itself in the chicken's cells).
- Approximately 10 days - death: Full replication of the virus is carried out and the chicken begins to "shed" the virus.
- Approximately 7 days -3 weeks: Lymphocytes carrying latent Marek's virus travel through the body, to visceral organs and nerves.
- Approximately 3-4 weeks: In chickens that do not develop resistance, the lymphocites in the organs and nerves undergo a transformation and become gross lymphomas. It is only at this point that symptoms appear and, sadly death often follows shortly after.
My interpretation was that each of the above events begins when the previous one ends. So 7 days + 10 days + 7 more days + 3 weeks = approximately 6 weeks (or more) for the bird to start showing signs of illness.
As it has been said before...this disease doesn't follow the rules. I've had two cockerels die already in addition to my pullets and one adult hen.
How is your chick today @seminolewind ?
