Take a deep breath, I have good news for all of us. Although everyone says there isn't, there IS a test for Marek's that does NOT require a necropsy! There are, in fact, at least two DIFFERENT tests for Marek's that can test on a live bird. Here is one of them: http://aem.asm.org/content/23/5/942.full.pdf The other uses a method of testing called AGID and simply tests on a blood sample. Here in California, UC Davis's California Food and Safety division offers this test for, and I quote a woman I talked to on the phone there, "a whopping $2.00 a bird". Yes, that is TWO dollars. You can have a vet draw the blood and send it in for you, or draw the blood yourself and just drive it there or ship it yourself. They also take samples from out of state, I believe, perhaps at a slightly higher price. Surely this is not the only facility that does these tests in the US. They're out there -- I'm not sure why more people don't know about them, but I thought it was time that everyone found out! May Marek's strike just a little less fear in your heart from now on!!!
