I think we all know thatMarek's is present almost in 100% of non vaccinated chicken flocks. It is a virus from the herpesviridae family. And like his cosine HS-1 that almost 100% of human havery it, the MDV is present in almost 100% of chickens. The difference is if the virus ERUPT and that is dependent on genetics AND ESPECIALLY IN STRESS LEVELS!!

She's asking if I have had Marek's symptoms in birds before.
