I have been trying to figure out the origin for months. Here is what I know. The end of last April, I purchased my first chicks in 40 years. I was gifted them as a Mother's Day gift from my husband and kids. I had waited so long to get some more! My whole childhood, through college, I had bantam chickens. Just backyard mutts but I loved them. I got 4 NNs, 2 golden lace bantam cochins, 2 red frizzles and 2 buff laced polish...all from the local feedstore, all from Privett Hatcheries. I went back and got 3 more NNs, 2 more polish and 1 more golen laced cochin. Those, were for my daughter. In the meantime, I went looking for SQ silkies. I found a breeder not more than 15 minutes from my house. I picked up 5 silkies from her. Fast forward 8 weeks. My coop was finished. I put them in it and all seemed wonderful. They loved the room. Then, on day 3, I noticed one of the silkies limping....3 days later, she died. 1 leg forward, 1 leg back. I posted on here. All said it was probably a head trauma. Now, I know differently.
Until I knew better, I purchased other silkies and more vaccinated chicks. I flew to NY and picked up a barred NN roo. Fast forward again about 14 weeks. A NN pullet got sick. 2 days later, she died. I sent her in for necropsy. The results, atypical Marek's or LL. Since then, I have lost all but one of the original silkies plus many more. Some vaccinated, most weren't. Now, they all are.
I contacted the original silkie breeder. She has never had any problems and I'm convinced that she is telling the truth. At least, I have to believe her since she is still selling eggs, chicks and older chickens. The only Silkie left is from an egg she hatched from a breeder that I have since found out has had problems with Marek's. Could be that natural immunity shining through.
At first, I thought it was the roo I flew to NY for...but, on hindsite, I realized that the problem existed weeks before he was brought in. So, I'm back to square one.

leadwolf1, have any of your flock birds had exposure to any chicken other than day old hatchery chicks or hatched eggs by you? It only takes one, as I learned, the only one I bought as a pullet.
Even a chick from a feed store may have been exposed. Vaccinated or not, if exposed, they can infect others, and the exposed chick not die from the side effects, just carry the disease.
