I couldn't find an answer in the Marek's FAQs and in my thread search. Sorry if I missed this information. If a chicken shows symptoms can it ever survive and recover? If it does, will it just die of cancer later? While you're reading, some questions about vaccination: I understand all Marek's vaccines cause the vaccinated chicken to be infected and shed the virus. I've read that the turkey Marek's vaccine, HVT, doesn't cause disease in chickens. If you only vaccinated with HVT would be OK to show and sell? If you vaccinated with the chicken viruses, Rispens or SB-1, should you keep a closed flock? Where can you find these vaccines? I've found HVT but not the others. Does anyone make a vaccine that includes all three? Rispens, SB-1 and HTV? Thanks!
