Thank you Kathy for the information on calling the lab in one's state. Good to know for future. I hope they can help Seabright's condition.Most vets won't give advice unless you have seen them a few times. Try calling the lab in your State, ask to speak with avian pathologist and see if they'll talk to you. I hate to say it, but I still think it's Marek's.
