Welcome to BYC. I am so sorry for your problems. I've read about Newcastle disease. I know that areas in California have that, and that, like Mareks, it can cause tremors and paralysis.
Do your birds have any respiratory related symptoms, such as nasal or eye discharge, facial swelling, or sneezing or coughing?
I would post all symptoms and pictures of the chickens, in the emergency forum. I hope someone will be able to help you with this heartbreaking issue.
Good luck to you and your hens.
