Thank you for sharing your experiences! It’s truly fascinating to read, although I’m sorry for all your losses.The way it was with my flock when I added vaccinated birds was that heck, it couldn't get any worse than it was. I was loosing 1, sometimes 2 birds a week from some truly terrible tumors caused by Marek's. My Welsummers and roosters were all hit really hard.
The weird thing is that I was able to talk to the head veterinary pathologist at Columbia School of Veterinary Medicine in Columbia MO when I came to suspect that I had MD in my flock and he told me that the birds that didn't die from the disease, that lived to 3-4 years without succumbing, would be my resistant birds and I needed to breed them for resistant chicks. It didn't work that way with my flock. I don't know how many chicks I hatched from my 'survivors'-25+? All but two died from various tumors, wasting and infections.
I suspect the weak link in the chain was my roosters, who didn't live past the age of 2. My Bantam/Amish barnyard crosses are 4 years old now (and bears the proud name of 'Old Man'), the oldest, that is. I also have 7 Silver Duck Wing OEGBs that I bought from Orschelns (the chick tub beckoned to me and I answered it's siren's call). They are working on their second generation and so far so good.
Maybe the theory that vaccinated birds as well as survivors do pass on a degree of immunity to their offspring. But if that is true, then why didn't my second generation Buff O's and Welly's survive? I'll probably never know.
Marek's is a complex disease and indiscriminate killer of both chickens and chicken owners' dreams. I had hoped to breed exotic chickens. Now I'm happy with my barnyard crosses and the fresh eggs and smiles they give me.


Maybe certain breeds are just more susceptible??? Both ones that have gotten sick so far have been Welsummers.
