I have read that wild ducks and geese (turkeys) are some of the main carriers but they will never exhibit illnessI do not think so.

Based on that necropsy report, I'd feel very confident you have Marek's in your flock. I'm sad to say that it's more common than people realize. For whatever reason, I see a lot of cases in CA.
I would strongly suspect Marek's over ALV (leukosis) because of the regions most targeted by tumors, as noted by your report. Especially the thymus and nerves. The thymus is often one of the first areas to grow tumors from Marek's (not always, but often).
Fortunately, from all that we understand, ducks and geese do not suffer from Marek's disease. I don't think that they are known to carry it, either-- though dander (dust, sometimes microscopic!) from a carrier chicken can get physically "stuck" to any bird or animal and be transported somewhere new. It's also known to travel on the wind, and some types of insects (especially those that like to explore chicken bedding then move on) can also transport it.
