I'm sorry for your loss.
I do have a question. What are your future chicken keeping goals? Do you plan on selling/trading/giving away hatching eggs, chicks, started pullets, etc.?
I really don't know the answer to your question. If you cull all and begin again at new property, don't carry over equipment/housing, have birds vaccinated, etc. You can probably start again once you get settled in.
Here's the thing. Even if you vaccinate for Marek's - the vaccination will only stop the formation of tumors but other symptoms of the virus can present (paralysis, respiratory, etc.). If these birds are for your use only and you keep a closed flock (all in/all out) meaning they never leave your property (live and die there), then you could conceivably cull heavily to "breed for resistance". I am not a breeder, but a few people do this, but they practice bio security and cull any that have symptoms.
Barbara @rebrascora has Marek's in her flock, so she may have much better advice than I could ever give. When you live it, you know it.
@Nambroth may be able to help as well, but I don't think she comes on as frequently.
